A bit further down this thread you can see how one of his counter-arguments consisted of telling someone his Android book had terrible reviews. What's funny about this is that it fits neatly with one of JTRIG's purposes of destroying reputations.
Although he did such a hilariously bad job of trying to destroy someone's reputation, I doubt he's anything other than a troll.
But now that I think of it, he did succeed in derailing a big part of this thread, so maybe he knows what he's doing.
