I think proper communication and what is appropriate depending on context is the real issue here. I accept garbled emails and forum posts because I realize that most of the world is not as obsessively compulsively anal as I am before clicking 'send'. They can get the same point across in 30 seconds of typing where I'm taking 5 minutes to dot the i's and cross the t's. Perfectionism is a horrible disease and there is no cure...
Texting, "How r u doing 2night?" is OK, even though I still can't bring myself to do it. Typing that on a keyboard is lazy. And what started this thread in the first place? An ad on CL about a "horny cokkege student trying to pay the bills", or something like that. Yeah, it's just a typo and it probably was a scam to boot but jesus, it's the headline for an advertisement - take a fucking look before you hit submit! If I see an ad for, "Me and my horny romy wanto fuk u, were hot", I ain't going there no matter how hot and how low your rates are. The brain is the most important sex organ and chances are, those types won't be stimulating it.
