I do, though more as GM than a player, and mostly using an increasingly battered looking copy of the 3rd edition Basic Set. I've read the Characters and Campaigns books for 4th, but haven't got an opportunity to play them (my group makes weird, slightly pained noises when I've got the books out), so I [i]think[/i] I qualify as having a moderate understanding!

I can work with this. I'll be honest when I say that I've only read C&C 4E and haven't GM'd a game longer than a week, but these were because of very bad scheduling and player apathy, which heightened my anxiety into flaking as a GM. 

But, hey, ever see Buffy the Vampire Slayer?
