Stumble upon is the coolest toolbar around. It really changes the way you use the web.
Just imagine a big directory of tags with a lot of people using this dinamically. People just discover websites and if they think it’s cool, they just press “I like it!”. So, if you chose tags like “humor” you’ll receive a lot of sites with humor content and just sites that other people likes.

In other words, all content is sent by people like you, and you can always chose “I like it” or “no more like this”.

Worth a try.
