Proposed improvement to flagging, for answers
I sometimes see answers that definitely fall under "low quality" or at least "too short to be an answer" category. They've been outright deleted, but in some way they do answer the question.
Here are some recent examples (the deleted answers in the blockquotes below). Sorry Diago ♦ for picking these out, but I only remember those recent examples – nothing personal! Keep up the moderation work!
It answers the question, it's that simple.
Photoshop already has keyboard shortcut
Control + Tabto switch between tabs.
Maybe the OP didn't know that yet?
You can also add transparency to image (10% should be enough)
Might help the OP, who knows?
These aren't the best answers, but in some way they are helpful. If these are deleted, this gives the wrong impression to new users. They want to help, but their content is deleted right away. This can lead to frustration, and even posting again. Example:
<rant>I originally posted the following answer, but a moderator deleted it, probably because it contains nothing more than a link. In my opinion, it answers the question perfectly and succinctly and I'm more than a little annoyed that my genuine attempt to help was just thrown in the trash!
So, please, if the answer is a genuine attempt to be helpful, but not enough to be an actual answer, don't delete it right away, but at least make it a comment instead.
I'm all for keeping high quality content, but I think we can all agree that a somewhat helpful comment and a happy new user is better than just deleting their (small) efforts. In any way, a small moderation message like "Your answer is too short, please expand" or "Please explain how this answers the question", etc. would be nice to have.
