No. Their are far worst grammatical atrocities.
Grammar is an artificial concept, and one that is of little use to anyone.
Language changes all the time, when a language ceases to change, it is dead. Deal with it.
THis. It annoys me without end when people say "ain't" is somehow improper.
I agree with you guys. As long as you get your point across without distracting the reader too much, who cares if your apostrophe's ain't in the right place or you've got a dangling participle...whatever the hell that means.
