People often point out existing solutions, so that's useful. Restricting it to a single account and once per month avoids the other problems of those threads.
I know that halfbaked covers some of the purpose, and there are probably reddit sub-reddits that do similar things, but still, and HN version would be good.
Will check out halfbaked, haven't heard of that. There's a subreddit /r/somebodymakethis which has occasionally had some interesting ideas (it led to RES) but there's probably better options.
There was a HN styled forum posted a while back too, (found it in the comments) http://firespotting.com/ - but it's definitely less active and a smaller community.
