Someone asked a question that didn't show a lot of effort. It had a two-sentence description of the problem, incorrectly identified a data type being used, and included no example (though one would have been easy to provide). It was a bit vague, but I had a good guess as to what the OP was asking and how to answer. Another user commented that a minimum working example would help a lot. I waited about 30 minutes (no edits) and answered. Should I have waited longer and/or commented to encourage the user to improve the question? If the answer is accepted, should I go back and edit the question to make it more clear?
In case you're curious, this is the question. The OP isn't actually a new user, but seems to be a very infrequent user and has a low accept rate.
