Yes he used to post on HN quite a bit, most of his posts get down voted into oblivion however because few knew who he was and his mental illness makes for some abrasive comments.
Objectively speaking, the comments were low-quality as published. To reach a larger audience, they would need some volunteers to separate and clean up the good ideas, and discard the nonsense.
A lot of his comments are "words direct from god" as determined by the random number generator in his OS.
I wish this was a feature on HN actually. It'd be nice if some accounts had the ability to "un-dead" a comment, in the same way that some accounts can flag or unflag posts and comments now.
I browse with showdead on and occasionally run across a comment from a submitter where the submitter was hellbanned for a specific incident but the comment itself is worthwhile.
