Just to bounce ideas/brainstorm. The issue is why would people come to this site to click 'I'd use this' or 'I support this'. (Ideas will flow in no problem, they're a dime a dozen.) So we need to provide feedbackers with incentive. 1. Reward them? Oops…nothing to stop them going around and supporting them everything and game the reward system. 2. Reward them based on their choices (and limit their votes)? Nope…these…
The other perk to this is that idea-submitters get a home-grown email list for their new app.
