Are VCs really *that* busy?
Some of them take 1-2 weeks to respond to an email even after a warm intro, but they tweet all day. Others you have to schedule meetings 2 weeks in advance. I know of 1 very high profile VC that is on a non-finance related forum I frequent and I see him posting and browsing all the time.
Do they just like to be busy to seem important or are they truly insanely busy?
