You didn't capitalize "AIM". ;-)bkev said:
I'm private-school educated, much to my occasional chagrin at lack of extracurricular opportunities. My good grammar/punctuation stems from the fact that I PO'd the wrong people on a forum 6 years ago for not using the proper kind - and, plus, in middle school most of the people I talked to on aim encouraged it. I had a bizarre group of friends, not that I'm complaining.
But yeah, I always use proper grammar and spelling, even on Twitter and texting.
