do you or might you ever post clips of your game playthrough streams, in a similar vein to the clips of your reaction streams on 3Bskyen?

Probably not, no. It would take the investment of a lot of working hours, and there just wouldn't really be a return on it, ultimately, at least not enough to justify the investment. It's one of those annoyingly business-brained decisions, unfortunately, but I'm already behind enough on all my other commitments, I really can't add clipping my let's plays to the pile of stuff I have to do :/
