on a side note I have been following Jack since Lee Torrens introduced him in Microstock Diaries, back in 2009 where he also posted his earnings around microagencies (kind of looking what would come out there) for sure Jack had tons of other stuff in other big agencies and pursuit other adventures, for sure a lot more interesting too, not only in terms of revenues
after that I have been following his twitter too and oh boy that gotta be one the most active twitter I have ever known or seen, he is everywhere and he knows everything, enjoy tons reading and following his tweets, articles, links, pics, advices etc very cool stuff
