I was wondering whether any attempts have been made to measure the time a user takes to write a post. It could be used to warn users (possibly only low rep users) that the question they want to post might be badly received if they don't show enough effort in their question.
My guess is this could eliminate some of the low effort questions of new users which still show up regularly. Instead of expecting users to read the faq before posting, a warning message can be useful for two reasons.
- The user can reconsider posting the question. Hopefully adjusting it before posting.
- The user gets an indication his question might not be received very well, preparing him for possible down votes. Nobody has to leave a comment redirecting him to the faq or anything, he already got the message.
As a clarification: as Joachim mentioned, this shouldn't prevent the user from posting. It should only serve as a warning message for new (low rep) users. If they feel their question is good enough as it is all that is needed is one extra click.
