BTW, the 20-25 year olds are not the IM generation. The IM generation are those waiting to be 20-25. The kids in high-school and junior high, heck, even younger than that!...All of them have cell phones, and there's a nice thick scattering of blackberries, PDA's, and all that teletype junk. They can't go 5 minutes without sending or checking their messeges.
Back on topic: No one's expecting anyone to be a grammar Nazi. That's a bit too much. What we do expect is that you at least show some effort. You can't tell me that the period key is just so much more of a hassle to hit than any other key. Give me a break. Yer not relaxing, yer just being overly lazy! If you want me (and others) to take you seriously, or more, to even UNDERSTAND you, then you should write your posts with a little more care. It doesn't take any effort at all.
