Don't stop at ideas for webapps. What about ideas for creating jobs or reducing environmental problems? I guess you could crank out other sites that used collective decision making fairly quickly, now that you have the template. Build a network of these sites and sell it to someone.

If you had groups for people to join it might make sorting easier; we still have to sort through people with ideas that cannot type URLs in a browser: http://news.ycombinator.com/item?id=1119184

Also, allow me to unvote. I accidentally clicked on voting for some top app to see how test how voting worked.

Please don't have me default post to Twitter when I vote for an idea after logging in with Twitter; that is sort of annoying.

Consider how search engines are going to index the ideas from your users. Create a URL object for each post and have the relevant content there. ( such as other users' comments about how to improve the app idea )

How do I submit ideas from the Wappr site?
