YC applications for the Summer 2015 batch are due in a week, so I thought I'd do an AMA to answer questions about applying to YC, how the program works, or anything else.
EDIT: 12:55 PM. This has been a really fun three hours, but now I have back to back meetings for the rest of the day. Sorry I couldn't answer everything--I typed as fast as I can :)
Special thanks to the YC software team for fixing an issue very quickly in the middle of this!
