i am sam lessin. i lead the 'identity' product group at facebook. before that i launched timeline and several privacy projects. I used to write a lot and stashed my old public writing here. I organize Y+30 originally in brooklyn, now in sf. I founded drop.io, created little projects like letter.ly, csvemail, and a bunch of other experiments to play with information.

i invest in some of my friend's companies when they let me, like venmo and makerbot and birchbox ... and love all things that have to do with skis and kites and my wife.
