I just tried it out and the interface is a bit clunky, but I like the idea. Indexing was far from perfect, and haven't tried out recommendations yet. However, in general, the idea of doing passive (meaning, implicitly gathered) collaborative filtering / recommendations on research is something that I find interesting, being a recommender systems mensch and all. This is one of the problems I'd like to see solved as a way of pulling in research that's in my field that I'm not yet familiar with, so I hope it works out for them.
