hehe, Academie Française makes me laugh. No, I prefer a much more democratic approach to language: that is, if you don't like the emerging grammar, beat it down!
I'm being silly, but seriously...just as much as it's ok for language to change by people insisting on new uses, the people who oppose such changes are an important voice as well. Sometimes, if the case is compelling, the Grammar Nazi's will carry the day and, hopefully, stave off the possible widespread acceptance of words like "irregardless." Other times, the Grammar Nazis will lose and it will become normal for people to say "ironic" when they mean "coincidental." Either way, it's democracy in action!
