How do you keep track of all your websites?

We've talked about Web 2.0 tools such as delicious and diigo as ways to keep up with your Websites and information you've found on the Web. This article discusses the Web 2.0 curation tools. One of the sites covered is Scoop It. It is kind of a combination between Stumble Upon and delicious because you can set up topics and it will crawl the Web for you making suggestions on sites you might be interested in. There is one draw back, Scoop It is in beta testing and you need an invite to use it.
