idea: finding experts locally

I sometimes read a paper, and think: how I wish I had someone around here to work on this stuff with.

If I could find someone at CMU who:
* cites this paper, or cites many of the same papers as this paper.
* has been a co-author or colleague of one of the authors
then this problem would be considerably simplified.

Some relevant resources:
* CiteSeer can be used to get the citation graph (although this can be problematic)
* citeUlike is a recommendation system. Might be useful.
