For one, we have also implemented n_readings that works pretty much like n_ratings into general-comments and new-file-storage...
I think that starting some non-tech specs on those modules (keep it short and simple) would be a good start.
Then we could ask for some more volunteers to work out something for
"Ratings, rankings, categories and pageview tracking coupled with profile/preference matching"
and additionally Don mentioned to capture skills and willingness to contribute, which would also fit nicely into this concept...
Note that in order to make useful matching, we need a high degree of categorization concerning member skills. This is the basis of the so called "yellow pages" in KM.
I know that this is over the hill, but as some people remember we had some discussion of how "hard" it is to contribute other than on bboard. We should maybe also work out a module called projects where community members can open up a colaborative space like http://www.groove.net where they can work with others (flexible permissions) on a certain project. I was working a little bit with Lotus Quickplace recently, and I thought it wasn't too bad either, although groove is a lot more mature, but therefore you have to download an application, while Quickplace is completely webbased. I always prefer completely webbased...
To check out more about Quickplace, you can get yourself registered and build one of your own. Webbased of course.
