I'm at the Ebay Developer conference and they just unveiled a new community for developers to showcase their projects.
What's really cool is their development radar. It's a community driven approach to evangelizing development. Basically, if you're not technical and you'd like a widget that does something wild with your watch list or current auctions, you can post your idea at the radar and a developer can build it out. It has some Digg like functionality where users can add their own "demand" for already posted functionality.
What a great way to connect developers to the community that uses their tools. Its a mutually beneficial solution - users get their functionality and developers get their audience. Pretty smart.
There's a huge push here to start driving buyers to the popular auction site - interesting stuff. The web really does give power to small teams - can you create the killer app that makes a mark on Ebay's income statement? If you can, they're giving away a PS3.
