I'll be interviewing them again this year, but they answer questions from the chat channel so you can talk to them yourselves if you like. 100% of the donations through ChipIn go to Child's Play and they accept any amount. Every little bit helps. Their first goal to play past level 20 is $800, but they're only at $310 as of this writing.
If you like the idea of watching people grind, level and take requests from viewers -- and I know you do -- head on over and hang out with them. They'd love to have you and the sick children they are helping will appreciate it too.
