Hey guys,

I came across a website which is kind of like a search engine for websites.
It works by a tag system so for example you could type "social" and recieve a whole list of websites relating to social networking.

Very nice and clean interface.. brilliant for use with my n800
Although because these are specifically web 2.0 sites they might need Flash 8+ to work, depends on whether they use advanced scripted APIs.

edit: does not work properly on n800
but still excellent site

That is a great 2.0 resource. Here's another called http://www.netjaxer.com which has a few hundred 2.0 sites and application that launches certain sites directly from a Windows desktop.
