TechStars requested videos this year, before YC's latest application opened, which also requested videos - are we to now start saying YC copied TS? Get over it.
I'm not knocking TechStars for doing a similar thing. I'm knocking them for copying it line by line (often by cutting and pasting) and not innovating at all. Good businesses often borrow ideas from successful competitors, but they never copy them entirely. They always seek to improve.
