BibSonomy is a system for sharing bookmarks and lists of literature. It now has a new blog.
When discovering a bookmark or a publication on the web, you can store it on BibSonomy. You can add tags to your entry to retrieve it more easily. This is very similar to the bookmarks/favorites that you store within your browser. The advantage of BibSonomy is that you can access your data from whereever you are. Furthermore, you can discover more bookmarks and publications from your friends and other people.
Why don't you just try it yourself? Any feedback is very welcome.
