It doesn't seem like a platform that will do him many favors, unless it starts developing features he's using on YouTube. His YT videos have multi-audio support so they can be watched in different languages, and I'm pretty sure X is single audio and also more compressed.
If it does pan out, at least the money will go into videos/helping others.
I got the FLCL art book from somewhere. I'll try to remember and find my sources, but probably tomorrow since it's late here right now.
