Yeah I'm not sure why there's even a grammar hate thread in the first place, but I just figured I'd point out the even more glaring one just to be thorough, hope you can take a ribbing 
Because grammar is quite obviously getting horrible in today's day and age for english in america. I'm not perfect of course, but i am pretty good at least in the area of then, than, there, their, and they're.

Bad grammar, even subtle, keeps me from taking
this site seriously and pisses me off (it's in my home state, and they can't use words right).
I could write that better than they could. You could too; a lot of us could.
