Speaking of sharing ideas, I'd love to get some feedback from you guys on a recent side-project I developed at http://thesparkfoundry.com . The premise is that you sign up for various mailing lists for voting on ideas and entrepreneurs can access those lists by agreeing to build them (http://www.sparkmuse.com/foundry/howitworks). Highly voted ideas would then be attractive to a developer as you'd get a built-in pool of potential beta subscribers or people willing to give feedback. Unfortunately I never had the time to fully promote it, but it was fun to build.
