ModNation Racers and LittleBigPlanet Karting still active?

I am interested in playing these games. Are people still playing the online?

LBK's online has always been kind of screwy, so if you're looking to play with random people, you might not have such a good time. I'm sure you could still find people to race with on Modnation Racers, but it's been years since I've been on that game so I guess I wouldn't really know.

k thanks

anyone else know if these games are still active?
