OK -- I call the bluff. Anyone want to purchase my fully vested, in the money stock from my Series A company? Please contact me offline, contact info in profile. I'll post later how many cents-on-the-dollar people quote for the stock. This alone is worth a whole HN post, and should be an interesting experiment.
