I used to do it years ago, but I ride less aggressively these days and don't really see the benefit anymore. Done properly, however, I don't believe it damages anything. That being said, occasionally I'll preload the shift lever in preparation for an upshift, hit a bump, and unintentionally snick it into the next gear when I wasn't expecting to. No foul.
