Due to wide spread popularity of stackoverflow.com among programmers, nowadays one can find the list of features that programmer would like to see on Stack Overflow. Some are genuine and some are jokes.
One such joke I found says:
Stackoverflow.com will introduce a new software testing service inspired by Amazon's Mechanical Turk, where developers upload their programs and testers find bugs in exchange for a micropayment. Somebody then does the obvious and connects it to a Mechanical Turk task that gets one bunch of monkeys to write code and uses the second bunch to test it. A reasonably good clone of Windows 7 is banged out over 8 months with a budget of about $4,000
I would be interesting to know your feature.
