I know a few bots have been identified previously, and it wouldn't surprise me if some had experimented with posting questions using code.
I'd rather not re-invent the wheel, and this seems the best place to ask.
What code do you have or know of that is capable of posting new questions to stackoverflow?
I'm working on http://stackoverflowoverflow.stackexchange.com - the idea is to take closed questions from SO and post them there for those that want to continue off-topic conversations in a stackoverflow-like environment. The code for posting to a stackexchange site should be essentially the same as code for stackoverflow. I've asked for code examples at stackexchange, but I imagine there are more SO bot developers here than there. I also know that if I post it on SO it'll get sent here post-haste, so here we are.
