Via Dave Bacon: CiteULike. Web site for tagging, rating, and sharing recommendations for academic papers, sort of like del.icio.us.

Has a few of my papers, but among all authors only a handful of papers tagged as computational geometry. Doesn't seem to be great at aggregating duplicates; at least, among their somewhat random looking sample of 18 of my papers, one has two entries with different links. Can generate bibtex from its citations; when I tried it from the computational geometry listing the results were only mildly malformed (used @proceedings for one paper when it should have been @inproceedings, and journal instead of booktitle within that entry), much better than Citeseer's.
