I'm normally pretty anal about such things as well but I have to admit my grammar takes a nosedive when I start posting on boards... Usually because I write in fits and starts even if I'm only writing a paragraph. I may type 5 words and then go make a cheese sandwich for a kid... come back and type 5 more words and so on. All of this to say I get rather long-winded and incoherent. It's a miracle if I find my spelling errors in addition to the rest.
But since we're on the subject of being anal about it... Dogastraphe - in your original 'jumbled' post - the phrase "the olny iprmoatnt tihng is taht the frist and lsat tlleers in a wrod are" is more or less duplicated in the same sentence.
It made me stumble a lot more than I was supposed to in that exercise! Did you do that on purpose? LOL
