This will probably get downvoted into oblivion (fair enough since it's a thoroughly unconstructive comment) but I'm really developing a pet peeve against comments that basically consist just of the word "This." or start with "This." and follow it with some tame form of agreement.

I find it about 2.44 times as annoying as someone commenting "upvoted". I now reflexively downvote any comment starting with "This.". I know I have no power to alter such a strong internet meme, but I thought I'd mention it to get it off my chest. Sorry for wasting your time with this post.
