I am still adding things to my account for even general interest. But i added libraries that I am interested in and ones within my local areas in regards to web 2.0 tools that they are using.
It's insane the amount of tools that are out there for us to be able to keep tabs of some of our favorite things to search online. Delicious just happens to be one of them and I have certainly found it interesting. I enjoyed being able to follow a tagged item that would further allow me to find similar websites and such to the topic.
