10 definitions of Web 2.0 and their shortcomings
I have come to avoid talking about this stuff with people. The first question anyone asks me is “what is Web 2.0?” Unfortunately for the ensuing conversation, it’s a little tricky to provide a straight answer. Every time you find a neat expression for summing the whole Web 2.0 thing up, I immediately think of an exception, or three, or ways that the definition doesn’t really get us anywhere.
In the list that follows, I’ve taken a lot of these characteristics or definitions from Tim O’Reilly’s What is Web 2.0?, and also Paul Graham’s Web 2.0 and Jason Fried’s user survey about the term.
1. The wisdom of crowds: We’re thinking here of things like digg that harness collective judgements to decide the importance of news stories. People talk about the power of ‘network effects’ when they’re keen on this definition. Google Search works like this by using the number and quality of inbound links to decide a page’s importance. But the whole idea does not apply to Google Maps, or any of the other Software-as-a-Service (SaaS) crowd e.g. Basecamp, Writely, 30boxes, etc., which are nonetheless thought of as being Web 2.0. Nor does it apply to social networks that are just about developing and maintaining friendships, like MySpace, though they do benefit from network effects, of course.
