I'm not sure this is the ideal way to go about it, but this contest (not being run by Twitter, I should add) is certainly interesting:
Following the rousing success of our Fix Digg's Miserable Business contest, we are hereby officially announcing the Create A Twitter Revenue Model contest.
After we decide on a winner, we'll post their plan and resume on Alley Insider as well as email both to Twitter cofounder Evan Williams. We'll post some finalist entries on Alley Insider, too.
That should be fun to watch :)
