Deidre: I say "like" ALL the time... but I think that's because I was born and raised in Orange County, California... I come by it honestly, at least! LOL. I'm really trying hard to stop saying it though now that I'm older... and DON'T live there anymore!
I'm really confused about that website though... it's from SUNY College... I wonder why they published incorrect information. Or maybe they just don't use AP Stylebook as a reference. AP Stylebook is the reference for media publications. In my opinion, that is the reference that should be used.
