I don't know anything about what might have actually happened or who said what back when, but FWIW when I first met Keith a few years ago (I only see him socially, not professionally) we talked about what each of us had done in the past and about TC all he said was words to the effect of "..and I was involved a bit when Techcrunch got going. Then I ...". The only reason this even stuck in my mind at all is my GF had earlier described him as having founded TC, so I noted what he said to correct my my understanding.

Maybe other times he played his involvement up more, and maybe other times Arrington played it up more (as have been noted in these comments) but literally the only time Keith ever mentioned TC in my presence is completely consistent with what Arrington says in this blog entry "is what really happened".
