I tend to use wikis for this sort of thing ... which admittedly may be the worst solution of all, except for all the others that have been tried so far. :)

From my limited googling on this topic, I get the feeling that this is a hard problem. At least, I couldn't find an example of an unqualified success story in this domain. For example, this post indicates that AnnoCPAN has hardly been an unqualified success. If anyone knows of a "successful" version of a similar concept to AnnoCPAN, please let us know.
