Arrington has an inflated sense of self importance. I'm quite sure that, he too, does not give a hoot about users, just about trumpeting himself. I had the opportunity to interact with him in person back in July and picked up a weird negative vibe and actually felt bad about it. Don't know what it was but the man just reeked of negativity!
not clear what the goal is. If the goal is to track workouts there are lots of better programs you should look at before expending too much effort on something that isn't significantly different.Hi-Tech trainer comes to mind.
