Citation? My recollection is that imgur didn't show up until after the Digg exodus and happened on Reddit first, but maybe I just didn't see the Digg side of it.
> I posted it on Reddit, Digg, and a couple forums that I frequent at the same time.
Imgur was never a reddit exclusive thing. It was just mentioned to advertise and gain loyalty from reddit users.
Which, honestly isn't a bad thing if he did.
