I pray no one proclaims they "could care less" about this stuff.
Honestly, I think a fair lesson to some people is that how you type (and speak) in almost any forum can and does affect the opinions of certain people... they may think you're dumb, lazy, uneducated, poor, or even the devil himself. Now, you may not care about people that would have a misspelling affect their opinion of you... that's fine. If you can live with it, they have to live with it.
I'm sure we all have more important areas in our lives to improve on as compared to spelling and grammar, but I understand how apparent ignorance and/or stupidity can get some folks excited.
To our Western Kentucky friends that may be reading this, hi! I bet you're impressed with our conversations on this basketball board! I saw some geek on there commenting on how posters on this site used a lot of 'periods'.. 'ellipses' may have been a better description, you towel waving freaks.
PS - I find it strange when people call a message board a 'blog' or 'chatroom'. It doesn't send me into a dpodoll68-like rage, but does probably cause me to make assumptions (i.e., this guy must be old... or.. this guy must be strange)...
