As I mentioned previously I went to the Future of Web Apps conference this week. The conference had the usual mix of interesting, not so interesting and sales pitches – here then is my take on the interesting.
Simon Willison gave a great, very entertaining, presentation on OpenID – which for those that don’t know, is a framework for creating a decentralised service to manage your online identity. OpenID uses a single website URL, instead of a username and password, to identify yourself with a site. There are a number of OpenID providers or you can setup your own, if you’re that way inclined.
Over the last few weeks both AOL and Microsoft have come out in support of OpenID – and I would love the BBC to replace their Single Sign On service with OpenID. Anyway, at FOWA both Digg and Netvibes announced that they too will support OpenID, this is great news; I suggest you should take this as a sign to find out more – 2007 will surely see an increasing number of services adopting OpenID and new business models enabled by it.
Netvibes also announced that they will launch a Universal Widget API (UWA) with the objective of “build your module once, deploy everywhere [Vista, Mac, Google, Yahoo!]”. As part of the UWA Netvibes are releasing:
- A UI library for widgets
- Netvibes also want to build a community of APIs
Other consistent themes included the importance of building an API into your web app from the outset, the use of attention data and being open and honest with your users; of these attention data is, to me, the most interesting.
“When you pay attention to something, or when you skip it, data is created”
(Matthew Ogle, Last.fm).
I suspect that we will start to hear a lot more about attention data in the coming year both in terms of functionality and generating revenue. For example, Flickr uses attention data to calculate which photos are ‘interesting‘: “We looked at how many times was a photo commented on, viewed, blogged about, and saved as a favourite” (Bradley Horowitz); or how Last.fm uses attention data to moderate the importance of user tags (if you listen to a piece of music your tags count more than if you don’t). And of course if someone knows what you pay attention to, and what you don’t, that data is incredibly valuable to advertisers.
