I know Mark Zuckerberg is the villain now, but let's be fair. Just because Facebook's default privacy settings aren't private enough for our tastes doesn't mean Zuckerberg is a psychopath or that everyone who has a grudge against him is the hero.
Frankly, I don't care how any lawsuit goes. My personal recommendation would be to take the settlement and cash out while Facebook stock is still worth something. I'm not terribly sanguine about the 1-2 year prospect of the stock. (Not because Facebook will be gone by then, but because the current value of the stock includes a promise of growth that I think will be obviously not going to happen by then.)
