Quoting a small part from the "you reached the question limit" page which appears when I press the Ask Question button:
It's been 0 days since you asked your last question. We ask that you wait -2 days before asking again. Use this time to revisit your previous questions, editing to address any issues that folks have pointed out in comments.
Now how much time am I supposed to wait until I can ask another question? -2 days?!?
EDIT: After one day,the message changed to
It's been 1 days since you asked your last question. We ask that you wait 2 days before asking again. Use this time to revisit your previous questions, editing to address any issues that folks have pointed out in comments.
