I enjoy some dubstep, but having tried to make it, I know it's not as easy as you think. I listen to more trip hop and glitch now, like Slugabed and Kuedo, but like the occasional Wub here and there.
I dunno if I'd qualify Skrillex as dubstep, while he uses wubs a lot, he doesn't usually subscribe to the rule I find almost more important than wobbles: half-step beats. He keeps a very steady four-to-the-floor beat on his wubs, unlike guys like Skream, etc, who keep that half step which gives it that off-feel. I like that feel best, which is why I like triphop and glitch and such.
And yes, its very much more production than you think. I can make a dubstep track (I have, actually... I got so many peeps hatin on me for it) but I'm still learning production, cuz I has no monies XD It's far more than just a wobble and a half step, it's usually produced until dead. That's the best.
