I'm not involved with Tapulous and therefore I'm not really at liberty to say. Actually I probably should have kept my mouth shut on this thread, because I despise when people do what I just did, but I just could not sit by while that credential got thrown out there as if Tap Tap Revenge was his brainchild or something.
I don't know anyone inside Tapulous personally, so this is pure hearsay. Take it as you will.
What I've heard is Mike thought Tap Tap was too low brow and that by focusing on that app to the exclusion of their other apps at the time (Twitterific and FriendBook) they were betraying his vision for the company.
After he expressed his opinion about this he was asked to leave.
I'm not going to contribute to the snowballing of this particular thread by adding what I know of what he did on some of those teams and companies he lists, but...exactly. It's his ego that rubs me the wrong way the most. The way he writes like he was instrumental in the creation, development and/or success of the apps he was involved in, when there's, oh, many other people that've worked with him that could list their credentials the way he does, except...wait. They don't. And there's more than one person on a team that makes things happen. sigh :(
