On Drupal Answers, the lists of questions (e.g. active or hot questions) show the person who made edit on a question as if it was the author, so I find this quite confusing.
You can see that googletorp, kiamlaluno or Berdir are omnipresent, but in fact they don't ask question; they just edit the questions to correct presentation, tags, etc.
I think it would be better to let the original poster name there and it would be gratifying for new users to see their name instead of a moderator.
