Hi,
I think that the following "per-tag" information would be useful for people, deciding in which of several related or seeming similar tags to ask a question:
- Mean time for receiving the first answer for a question.
- Mean time for the first upvote to a question
- Mean time for accepting an answer.
Imagine you have a pressing question and need a correct answer asap. There are two or three tags that sound similar and most-related to the question. Having the 1, 2, and 3 statistics above, you see that the mean times are lowest for one of the tag (the other two are not so well visited by the experts), and you chose this tag, based on the useful statistics.
Were not the statistics, you may not have chosen this tag, because you didn't think it really belonged there. This may also change your understanding about the question and into what area it falls most.
