It also bugs me when posters (not taking a knock at anybody specifically; this is just a general internet community observation) become spelling/grammar nazis. Of course, I understand and appreciate if somebody tactfully corrects common mistakes (i.e., confirmation vs. conformation), but it sometimes crosses the line into nitpickiness and even nastiness.

I was an English major, so I'm confident in my use of the English language...

...but sheesh, we all make typos sometimes! And it's important to remember that not everybody has access to the same level of education that some of us may take for granted.
