I love the inherent fact that they're essentially making a more solid and lucrative "exit" on an idea they probably only discussed at length and put no actual work into. Realistically they probably make out better from this (all things like time, effort etc considered) than if Zuckerberg never does Facebook.
I take that $20 mil in cash and $150 mil in stock, and if it's really not about the money like they say, I use it to be an angel investor or start other companies. This whole thing is getting tiresome.
