I thought about it first
Some time ago I wrote a blog about a piece of software I thought it would be cool de have. Now, thanks to friedapplepie I've found out someone is building something similar to what I thought. I'd still want a citation tool that worked with my work processor and way of including articles as well as books, but it cool so far. It is called The Library Thing and is a beta version now. Let's see where they take it.
