New search tool for science!!

I just tried out Scitopia, which describes itself as a "...free federated search portal to the digital libraries of leading science and technology societies." Currently, it simultaneously searches the publications of 15 scientific societies (including AGU), as well as "patents and government data" (I haven't figured out how well the last part works yet). It's in beta now, so give it a try and let them know how to develop it.
