I don't. I simply don't have time.
Part of me thinks if all this existed way back when, I would have ended up a much better drummer. It's so easy now to see how a particular groove, fill, song, whatever is played. As opposed to trying to figure it out, thinking maybe you have it when you don't, or finding out the only reason you don't have down is because the drummer put the tom/china/whatever in a different spot that makes it easier to play.
And with so much information, it's easier to see how much great talent out there their is to keep up with. Rather than being a teenager in the 80's, hearing Bon Jovi or whatever on the radio and thinking, ok, I can do that, so I guess I'm doing alright.
On the other hand, I if I were a young drummer today, I think it would be too easy to just get distracted and forget to actually practice (see Bo's post).
