I was reading this post where Jyrki writes:
I have come to think that answers that clearly required less than ten minutes of processing from the part of the answerer should be just left unposted. There are a few hit-and-run-operators that make me want to introduce rate limitations for answerers as well. 6 per day, 50 per month is generous enough. Focus on quality, not quantity. The answerers are not sitting in some exam here. After you reached 10k by answering calculus, leave that arena to the noobs, please (unless you can add a genuinely different point of view to that rare question where a new pearl can be found).
I think this is an excellent idea. It would stop answering machines who answer any and all garbage questions and it would stop general rep farming.
Do you think we should rate limit answerers? Is this even a possibility of the software?
