I was thinking about this as I read through a few topics and I know there are some posters who have the gimmick of making their point below the sig line. It's a fad or meme or whatever, I don't get it because I'm not hip to the young cats I guess. To me, everyone's sig is like a Shakespearean aside, sans the audience. Or when you are having a discussion and you think it ends then someone mumbles something behind your back.
Ultimately I think this fad is hurting the overall quality of discussion around here and I would implore those who do it to keep it above the line. Above the belt, so to speak. Sigs are fine, I've just noticed an increasing number of people claiming they've faked me out/trolled me/etc because they posted something utterly contrary to their main post as their "sig" and I couldn't be bothered to read it.
You sound like you're talking to yourself or trying to hide something. Make strong enough points that you don't have to take pot shots and then you'll see how weak your faux snarkiness is.
