For a simple forum, should I use bbPress or is there a HN/reddit style one?
jsdalton: I can't remember where I heard good things about this one, but I believe I did at some point:http://getvanilla.com/You might also look into whether http://intensedebate.com/ would work for your purposes...it does have threading and voting.Finally if you or your developer(s) know Python/Django, you could check out the following two Django plugins:http://code.google.com/p/django-threadedcomments/
http://code.google.com/p/django-voting/You could pretty easily put together a threaded, votable discussion thread based on these. (In fact, you can find a whole lot of other social networking features in Pinax, which I'd describe as a social networking framework for Django: http://code.google.com/p/django-hotclub/)Hope some of these suggestions are helpful.
