Daniel said, "I'm shocked at how, in a forum on proper usage of idiom, so many people misspell words and make embarrassing grammatical errors... refused to capitalize his I's. I don't mind that people write in such a way on forums generally, but on a grammar website I suppose I just expect a bit more."

Well, are you being ironic there with your misuse of the apostrophe in "his I's". It's plural, not possessive.
