Yes, it seems to me that puredata.info is already the place for this.  I'd rather put the effort into making puredata.info friendly than further fracture the community.

First, you can already create your own "self-contained" universe inside of puredata.info if you'd like to start from scratch on making a usable patch-database.

Second, I think puredata.info would greatly benefit from some simplification, since the less things there are the less there is to argue about : ) (more seriously: usage would dramatically increase if we removed the cognitive obstacles of using the site).  I just dug this out of my bookmarks:  http://www.37signals.com/papers/introtopatterns/.  I think a process similar to this would be a nice way to start.
