I think that there are some interesting ommissions from the list, though… How is Last.fm not up there with the best of them? The site embodies all that is “web 2.0″ – Its social, innovative and useful. It has also generated a massive amount of interest on the net, too.

YouTube may be a winner when you look at visitor figures etc, and the fact they have been bought out, but just look at how much money they lose! The only people I can see having “won” from YouTube are the shareholders! (Oh, and the visitors, although it is certainly a victim of the theory that you cant have a high volume of high quality information/product… There is so much crap on there its not even funny!)

Wordpress really doesnt need to be up there… Sorry, it doesnt even belong up there. Ok, so its a blogging engine – Great. But that alone doesnt make it a “web 2.0″ winner. Blogging doth not make web 2.0. Sorry. The sites that index these blogs, that have a community etc, fine… But Wordpress is simply a tool… An enabler for the community driven content that is web 2.0 – Not a web 2.0 “thing” in of itself.

One more issue I have… Someone up the comments list said “they dont even use web 2.0 technologies”… err… You need a bit of correcting there, mate… xmlhttprequest is not a prerequisite for a web 2.0 site – “Web 2.0″ is all about the web as a social space – a “sphere” if you will. Its about users driving the web forward, and creating the content, as opposed to large corporations. Its the web controlled by the masses. Not about a bunch of flaky technology, which will be replaced before you know it. The themes will still survive long after the echnology is dead.
