Idea Description
Ideablob is great, but it looks like it's ending soon. I propose ideablob neXt: a website much like ideablob, funded by the 10K we win here, that will continue to give out money for the best ideas, Ideablob style. Unlike Ideablob, non-business-related ideas will be accepted.
What will you do if you win $10,000 for this idea?
Some amount of money goes towards web programming and hosting; the rest goes out to ideas, ideablob style. Maybe $500/month, or variable-rate prizes; we should be able to make this last at least another year and then regroup from there (ideablob neXt neXt?)
Vote for it now.

The easy answer seems to be corporate sponsorship, a la Advanta. Crowdsourcing (http://en.wikipedia.org/wiki/Crowdsourcing) is hot right now. I'd contact more web-centric companies and see if there is any interest in sponsoring a similiar site.
