An Open Letter to Facebook's Founder from Professor Davidoff (a lesson on deal terms)

"Facebook raised money in three rounds, seed money in 2003 and traditional venture capital rounds in 2005 and 2006"

Not to make a big deal about a typo, but Fbook launched 2/04 and got funding later that year from Peter Thiel.

Less like an actual "open letter," and more like a "here's a little lesson on uncommonly performed business maneuvers." The tone is kind of patronizing/offputting.
