Yes, I probably would try make a small investment in his next venture; not because I think he can recreate the same wealth he's done with FB, but his FB journey suggests he can make money again. I would still regard this as a bit of a gamble though. Would you put $10k / $100k / your life savings into his next venture without knowing what it is?
