Not many animators on /3/ either. But there are a few.
While there is a lot of similarities between the skillsets needed for 2D and 3D animation there is a pretty big differance too.
Both require you to understand how to make readable poses and develop a fine tuned sense of timing, know all the classic animation rules etc.
But in 2D you always know the final camera angle, and you get to morph your drawing to fit the frame however you please.
The final animation is at a low framerate and you really on the brain of the observer to make up the missing information.
In 3D it's not always known where the camera is gonna be, and you have a more rigid geometry that need to actually transition smoothly from pose to pose.
A lot of your time animating 3D will be put into tweaking interpolation curves for the inbetween frames calculated by the computer.
To be really good at either though require the same difficult-to-obtain understanding of mass, motion and time.
Since classic 2D animation is sorta archaic these days the crowd here is probably your best bet for finding people familiar with animation in general on 4chan.
