Would love to see a blog post that summarizes where WPMU and Buddypress are as far as social bridging are concerned... maybe highlight plugins that are a best fit with the platform, as well as any tricks or work-arounds. I've noticed the chatter, but would be great to have a consolidated reference guide somewhere.
Also would love to see some type of ratings capability (thumbs up/stars/favorites). For events, the thumbs up/down can be switched to "im going/not going." And, of course, with ability for user to have ability to also share this in their facebook and twitter timelines.
Disqus (or similar) Integration
Content sharing to 3rd party sites in addition to posting to wire.
Does this already exist? Am i missing something?
