2007 Web 2.0 Awards (from a company called SEOmoz)

Here is a a great window onto the world of Web 2.0. The 2007 Web 2.0 Awards come from SEOmoz, which is a "Seattle-based search-engine optimization company." There is a nice index of these in the Award Categories, from Books and Bookmarking, to Hosted Wikis and Podcast Services, to Mashups* and Widgets **.

* A mashup is a website or application that combines content from more than one source into an integrated experience. (Wikipedia)

** A web widget is a portable chunk of code that can be installed and executed within any separate...web page (Wikipedia)

This is, again, overwhelming if you don't have hours to spend or a very specific goal in mind and some previous experience. Check out the Color Blender (1st prize in Visual Arts) as one example of some cool free stuff!
