This answer came up in the review queue as a low quality post (no surprise there). I'm not certain what to do with it.
1) I have no knowledge of the subject
2) It seems there could be better/more explanation, but (refer to #1) I don't have the knowledge to provide it, so editing is not one of the options for me.
Since it could be the correct answer and just needs more explanation (at least as an answer on SO) I don't think voting to delete is the proper course, but "Looks Good" seems quite inappropriate too. Maybe "Not Sure" and leave a comment on the answer asking them to elaborate a bit?
