I was thinking about this site a long time, and started work few days ago, before all these recent discussions. I have always had too many startup ideas, and not enough resources to use them.
It still lacks some serious features, like voting, tags, private ideas, friends. I'm not a CSS wizard, so the stylesheets probably have their own problems too. I even not incorporated yet.
I initially wanted to wait, but it turned out to be a bad move. Hope you'll enjoy it.
