In 2005 I was just graduating from CMU. I remember when Facebook came to campus. They picked a large lecture hall to pitch their job openings. I want to say Facebook was way less than 100 employees at the time. In the lecture hall (which probably sat 100) there were about 20 people. I already had a nice full-time offer lined up - and remember thinking - why would I ever want to work for a company whose users "poke" other users. What value is there in that? #doh
