Building on the success of MVP1 (over 200 votes and plenty of feedback) we have improved the voting system, added the ability to attach a comment to your vote and improved the design. Check it out; anyone can vote and comment on MVP2.

(Note: We will be taking a limited number of project submissions shortly. If you have a project of your own, a minimum viable product or even an idea you are considering, you can leave your email address and we will let you know when it is ready to add projects.)
