I was reading What measures have been/can be taken to guide guests & new users with respect to the rep requirement to comment? and I was reminded of what had seemed to be a trend lately of people posting such "Answer-comments" and having them be transformed, and whether it was a good idea.
Specifically, I feel like we may be encouraging people who lack sufficient rep to comment to instead post an answer, knowing that it will be converted for them. On one hand, that seems mildly absurd since anyone who'd read enough of the site to know that we routinely turn such answer-comments into actual comments ought to have, or be able to accrue, sufficient rep to comment. On the other hand, we do have lurkers who may be quite familiar with how we do business, but have never registered an account.
Ultimately, this is not something I see as a huge issue, but it occurs to me from time to time, and now seemed like a good time to bring it up.
