I feel like this Jack Dorsey profile is fake, because he hasn't mentioned Peepeth on his Twitter account or anything.
However, it seems to have fooled the real(?) Fred Wilson.

Not that I think this says something bad about Peepeth... the situation is obviously not much better on Twitter, even with verification. Just a point about how easy it to be fooled online when you're not expect it...
