I'm getting this message:
You can only ask 6 questions in a 24-hour period
I understand we don't want users flooding the stack. However, when these 6 questions are good, then why not allow the asker to post more?
I'd propose changing this limit (and limits for other time periods) to count only questions with a non-positive score. If a user's questions are being upvoted, this means the user is asking good questions, so why not allow him to ask more?
