I understand typos. I don't like them, but I'm guilty of committing them, so I get them. But, as I see it, there are two types: (1) the typo that looks like a typo (e.g., teh blatant missed keustroke), and (2) the typo that makes the writer look like an idiot. Last Friday, I was guilty of the latter. But I'm not an idiot (not for this reason, anyway), I just didn't catch it until this morning.
The correction in the original has been made, but it sat there all weekend. So, to you grammarians out there, I apologize. I have already kicked myself in the teeth repeatedly.
In the future, feel free to catch my mistakes for me and drop me a line correcting me. Thanks.
