When does NOW matter?

Real-Time Web!

Like me you may well be fed up of hearing and seeing this term. However, I’m guessing that you’ll be fed up for a different reason to me. I’m actually very excited about the real-time web (I’m sure you’ll have noticed) but I want to see it used as more than just a buzz term. I want to see real-time used in the true sense of the term – to mean that something has happened within the last few milliseconds. I want it to mean that the tweet you are reading, the picture you are viewing, the status update you are reading, the event you are being notified of is happening NOW.

Google no longer takes days to index a web site or find a new blog post. For things like blog posts, new web sites, certain types of news and future events it doesn’t really matter if we only find out about them within hours of their availability. But with other things such as live events, breaking news and opportunities, seconds, and sometimes milliseconds, really do matter.

When does instant real-time matter? When do you need to be informed that something is happening now? When do seconds, or even milliseconds, really matter?

Here are a few examples that I can think of:

Live events – notifications related to live events completely lose their context if they are delivered too late. With live events seconds matter. If there is a system using the live event notifications, such as a betting platform them milliseconds matter. As soon as a goal is scored in a football match betting needs to be temporarily stopped until the odds can be updated to take into account the new scoreline. A good example of this is PickLive Football (previously Football 3′s).
Alarm notifications – If you have a system hooked into your house alarm, or a power system alarm then delivery of the alarm notification needs to be instantaneous so that it can be quickly acted upon. So, a firm such as AlertMe would probably be very interested.
Opportunities – If you check in to a cafe using a platform such as Four Square or Gowalla then there is a finite amount of time during which that location update will be valid. During that time there is opportunity for people to meet up with you. Another example might be that an unscheduled event is all of a sudden is taking place. Without instant notification of that event you would miss it.
Collaboration and communication – Good examples of this are instant messaging and Google Wave. I’m sure there are loads of other platforms out there where instant updates are required to ensure that people aren’t left waiting for a reply and don’t spend time composing a replies that are irrelevant or out of date.

I’d love to get your feedback on this so please leave you comments and ideas below.

Using real-time web software and technology to distribute events

How real-time does real-time have to be?

Phil Leggetter — Wed, 09 Dec 2009 09:37:45 +0000

Last night, just over 12 hours ago, I attended the Gary Vaynerchuk Crush It event organised by Sprouter in London. I’ve already read Crush It and seen a lot of Gary online so I wondered if he would give out any information that I hadn’t already heard. On the way in I mentioned this to Ian Sanders who said:

It’s always different live. It’s like a gig.

This is a big statement considering the event is just a guy standing and speaking and taking some Q&A. However, Ian’s statement was spot-on. Gary oozes charisma and when he speaks it feels like he’s addressing you directly. This is clearly one of the reasons why he’s so popular and doing so well.

One of the things that Gary covered, and I’ve heard him mention a few times now, was small town rules. My take on what Gary means that social media has made a global community possible. He provided a couple of examples.

Example 1: Small Town

You can go out in New York, get drunk and get naked every night of the week and it most probably won’t impact your reputation. However, in a small town if you do this just once it will.

Example 2: Small Town effect through Social Media

The movie Bruno (I’m not giving it a link, I’ve heard it’s that bad) had one of the biggest attendances for an opening night in the states. However, the second night had the biggest drop off in attendances ever. This is because on the first night people left half way through and wrote on Twitter and Facebook how terrible the movie was. In 24 hours word had got out to avoid this movie at all costs.

What has this got to do with the Real-Time web I hear you ask? Well, in the first small town example it’s easy to see why and how news spreads so quickly. In a small town it doesn’t take long for news like this to spread. But in the second example the news spreads to a massive number of people because of the real-time web effect introduced by the immediate availability of information from networks such as Twitter and Facebook.

I managed to get a question in and asked Gary:

How real-time does real-time have to be? For example, the newly introduced Google real-time search checks every 20 seconds to see if any more relevant search results are available.

Whilst Gary said that 20 seconds was probably alright he did suggest that this would be fine until another site provided the results in 19 seconds, and ultimately 0 seconds. At which point expectation would be changed.

This has encouraged me to continue my push to encourage the uptake of technology to provide a truly real-time web experience. Data is available instantly so why not push it to users instantly. Is 20 seconds really good enough when technology is out there to allow that information to be pushed to us in closer to 0 seconds? My opinion is: C’mon Google, you can do better!

The ChristmasCrunch nearly real-time web event

Phil Leggetter — Tue, 01 Dec 2009 22:07:37 +0000

On the 15th of December I’m going to the ChristmasCrunch. It looks like a really good event with Iain Dodsworth and James Whittaker of TweetDeck giving the keynote on “Where the biggest realtime desktop application goes next” (I know where I’m hoping it goes. See below). Other presentations include Jenni Lees of Festbuzz, Marco Kaiser of Seesmic, Mario Menti of Twitterfeed, Mark Rock of AudioBoo, Nick Halstead of Tweetmeme, Daniel Tenner of Woobius, Willian Fischer of Twitter Jobsearch and Tim Morgan of Mint Digital. And if that’s not enough there’s also a startup pitch (startup pitches – grrrr…) and an after party.

My main interest in this event is to see if anybody is going to start delivering a “truly real-time” experience to users. Will TweetDeck still be making polling requests to the various services it uses to check if any more data is available or will they move to using PUSH technology? Are other companies going to start adopting PUSH to give the user a truly real-time web experience?

I’ve already mentioned my opinion time and time and time again that what we presently see as the real-time web isn’t in fact giving any of us a truly real-time experience, and this won’t be the case until data is pushed to us in real-time. If we have to actively check to see if there is new data available then how can anybody claim that we are receiving data in real-time? As soon as the new data is available we should not only be informed about that new data, but also given it.

Let me use Google search as an example: Google is getting really good at almost instantly picking up new content on the web – what everybody is calling the “real-time web” experience. I’ve also observed that it looks like they’ve started to rank new content higher, so they are really embracing and valuing the freshness of information. If I were to go to Google.com and search for “Real-Time Rich Internet Applications” I’d get a number of relevant and potentially fresh results.

If just after Google returns these results to me Robert Scoble decides that RTRIAs are the next big and publishes a blog post on the subject, leading to a number of other blog posts and tweets, I’d be none the wiser until I resubmit my search to see the updated results. Google would no doubt pick up this new, high profile bloggers, blog post and it would be available, maybe even top in the search listings, when I next searched for “Real-Time Rich Internet Applications”. But, I’ve done my search and I’d believe that I have got the most relevant information available at that moment so my search results would be out of date.

Until companies move away from the old PULL web model and move to PUSH we are going to be stuck with a nearly-real-time web experience. I hope I get the opportunity to ask a few people at the ChristmasCrunch about when, not if, they will be moving to a PUSH model to deliver a truly real-time web experience to their users.

Why Comet is key to the Truly Real-Time Web

Phil Leggetter — Sat, 14 Nov 2009 21:01:57 +0000

A lot of websites use HTTP Polling to update data on on their website or application without the need for the user refreshing the website. This is clearly better than a purely static page, but during the time between each poll the data on the page has the potential of being out of date (stale) so to make a decision based on the information on a potentially stale page can be a risky one.

The normal example given to show the benefits of using Comet to achieve full HTTP streaming and the importance of non-stale data is of a trader making a trade on an out of date price. Another example is given where a person places a bet using odds that are on screen but do not match up with the odds in the betting system.

I just read a post on Comet Daily about a company called Frozen Mountain who have just released a component that adds Comet Support for IIS. Along with this they’ve released a video which doesn’t cover the standard example.

It’s possible that in this example that a polling solution might actually be just as suitable but this is a good demonstration of the benefits of Comet. In the example Comet provides almost instant feedback on the number of available tickets to potential buyers. This has two benefits. The first is that the user (Bob in the video) has less of a chance of missing out on his tickets. The second is more of a commercial benefit in that the user gets instant feedback on the popularity of the event and availability of the tickets and is more likely to make an instant purchase.

Until a solution such as Comet is used the data that a user sees, in a event booking, trading, betting or even search system, cannot be classed as part of the truly real-time web.
