Trade Chat, as you know, includes a lot of things besides Trade chatter: Guild recruitment, LFG, general help, gold spam and, of course, every topic under the sun. It also includes a lot of typos and grammar errors. Some of them are pretty benign, but others are so bad it's hard to decipher the meaning. And then there are the pet peeves.
You're a literate bunch. Do you correct people in Trade Chat? If not, do you mind or care when people do? And doesn't it take longer to type "ne1" than it does to type "anyone"? I know it does for me.
