No but seriously: why is a $900MM company that's 5 years old joining a "startup school" that usually invests ~$100k? /cc @sama

@seldo what we do for late-stage alumni is obviously different than cos in the batch, but still important

@sama Follow-on investment is totally rational, I mostly don't understand why it's attached to the YC brand/investment vehicle.

@sama Is YC really putting $100k into Quora? If not, it's a different type of investment, was there no mechanism to invest otherwise?
