Can you tell the history of the Internet without mentioning Schwartz? I'm dubious if you answer "no" and so he should be included for that if nothing else.
It is odd that Wikipedia is voting whether he is generally of no account or value worth mentioning. It would make more sense for Randal to vote on whether Wikipedia is of value and worth mentioning, or should be deleted instead. No doubt Wikipedia is notable, but mostly in the sense it is notorious.
