Grammar Girl!

She has great articles about apostrophes, then/than, effect/affect, and the like.

I often feel I need therapy to deal with my reaction to apostrophe abuse and what seems to be an up-and-coming victim: the ellipsis. I have a co-worker who is unable to use a single period in her writing. She separates all sentences with an ellipsis (and generally adds one to the end of a sentence). I think she's trying to say that all of her thoughts--all of them--are unfinished and she is unsure. All I know is that I cannot take her seriously. In the last several years I have noticed a lot more ellipsis abuse, especially associated with casual writing in email and in forums. OK, fine. But DO NOT USE ELLIPSES IN PLACE OF REAL PUNCTUATION IN EMAILS THAT GO TO CLIENTS! Not that I feel strongly about it or anything.
