I am one of those dinosaurs who not only dislikes abbreviations, but also dislikes poor and incorrect grammar. Evolving language or not, there are still some rules! Common misspellings also irk me because everyone over age 10 ought to know the difference between to, too and two or their and they're.
On a message board like this, grammatical errors or typos aren't a big deal. I make them and almost everyone else does at some point, too. But when I see errors in formal letters, advertising or in newspapers I really get annoyed! Newspapers and advertisers pay editors to avoid those things.
Oh, and this makes me, recall, the, excessive use, of commas, by some posters, here.
