Yes some still scratch. Mostly turntablists or dj's that play Hip Hop and other broken beat styles of music, D&B, Breaks, Dubstep etc. Generally the more important scratching is to a dj the more likely they are to still use an actual turntable or their digital equivalent. Trying to scratch with a CD or media player doesn't feel the same. It's harder and they feel like a toys in comparison to a Technics turntable. You really need the rotational mass of the turntable for scratching.

Dj's like myself that play electronic music typically use CD/media players, Midi Controllers or DVS (digital vinyl system). Although I still have my turntables and I actually just bought a third but not for djing. I just don't use turntables for djing much anymore. I use a midi controller for djing now, DVS before that and turntables before that. I don't scratch. You can do a lot more with the digital stuff like sampling and looping.
