I'm supporting a proposal to create a new Q&A website for programmers solving problems (and competing) on sites like Codechef, Topcoder, Codeforces, SPOJ etc. and contests like ACM ICPC, Google Codejam etc.
It's built on the same software as stackoverflow.com, a hugely popular site where over seven million programmers help each other with difficult programming problems. On Stack Overflow the audience votes for the best answer, so the answer you want is usually right at the top, not on page five.
I'm hoping that a site for programmers solving problems (and competing) on sites like Codechef, Topcoder, Codeforces, SPOJ etc. and contests like ACM ICPC, Google Codejam etc would have the same kind of network effect and turn into an amazing resource.
The proposal process is going on here:
If you're interested in participating, go to that URL and click on the green "Commit" button.
What's most important is that we need about 50 more people with 200+ reputation on any of the other Stack Exchange sites. So maybe get on Stack Overflow and post or answer a few questions to get some rep there :)
