For a while now there has been the GetOutfoxed community focused around the Outfoxed browser extension.
The company and the extension
A few months ago the project started to get "real" with investors, and office space, and desks, and chairs. They've now relaunched under the name "Lijit" as in "legit" as in "legitimate" as in "what you would say about a page that you think is good". This is an interesting project to me because it uses some of my favorite technology, it's a company in Colorado.
The extension is basically a way to say that something is "good, bad, or dangerous" and you can apply that rating to web pages or domains. Then other people (your friends, family, coworkers) create a trust network listening to your advice and giving you advice (the network connections can be one way if someone trusts you but you don't trust them). It's pretty clear to see that this could be extended from just web pages and applied to other things in life (email senders, operating system processes, etc.) and all of a sudden it's great. It takes a lot of cool products that have been going around takes them one step further. Really brilliant stuff.
Drupal Site - Pretty Theme
Additionally, they've got a really pretty page layout - pretty standard stuff in a lot of ways: The section across the bottom with categories and links within those categories. Right hand navigation. Fixed width site. Fancy 3-d Logo (though it could use a dropshadow). I'm not a super huge fan of the colors, but what I am a fan of is that when you look at the site it's clearly got a designer's hand in the look and feel. Many people complain that it's hard to theme Drupal - and yet there are so many examples to the contrary, this being one.
That's about it - help spread the love, won't you? And Digg the new Lijit site.
