Actually, i think it friggin sucks that there's no sig allowed in texts. I text people all the time that have gotten new phones, or don't text/call often and they may not have had my number. I get responses asking " who is this?" So, it would be nice to have.
I'm wid you. I don't see the need for a signature. My sister be putting all sorts of crazy crap like "! 10V3 y0u" or "@++!TuD3" attitude I guess? lol I'm always thinking its some kind of short hand thats part of her message to me
