Geonotice improvements (although I'm far from the first to think this would be a good idea)
Real-time chat - Integrated social networking functions and real-time communication channels
Sponsor a "Wikipedia loves Threadless" design challenge - we need good t-shirt designs
Host a microblogging service - Integrate something like identi.ca into the Wikimedia projects
Add game-like features - Teach new users the ropes and give incentives to all users to complete important tasks by offering "quests"
Proposal:Develop a copyright enforcement system - Help contributors seek redress when others use their work without respecting the free licenses
A new open reviews project, basically a free-as-in-freedom version of Amazon.com does (coming sooner or later)
Proposal:Tools for tracking reuse of Commons media - Automatically track where stuff from Commons is being used outside of Wikimedia
