Thanks for engaging in good-faith! I think that the average TA has to respond to the same question 100+ time or explain the same concept or correction, having a TA helper is useful. Sometimes TA's aren't available for profs, so this will help them spend more time mentoring students or researching.

This is so cool, thanks for sharing it here. Sorry for the aggressively rude responses, we are still working on our manners here I guess.
