I'd just like to advertise an interesting extension to firefox. It's called "stumbleupon". This is how it works (I've seen similar things like this before):

Someone goes on a site. They rate it. Others with similar interests click "stumble", and they might come accross that site (so long as it was rated positivly!).

As an example, look at all the good things people have said about this site:
http://www.stumbleupon.com/url/hexus.net/

Post interesting sites you stumble upon here - I'm sure this could be a way of finding some of the more interesting sites out there .
