Indeed! It seems like every day grammar gets worse and worse, and yet more acceptable. The common argument is that "you know what I mean", but that's a pretty lame excuse. Somewhat of a related subject is that spelling has gone down the hole too. When I went to school, spelling always mattered. Nowadays they don't force it as much. They are much more focused on the content, and although I can't argue with wanting good content but the spelling is equally important. You come off looking foolish when you can't spell properly. I know spell check catches a lot, but it doesn't catch everything. I will admit that I have at times in my life used "could care less" but as you said, I have changed my ways.
