I think you've hit the nail on the head Meg - possibly the problem is the Pathfinder/Roll20 combination & our general tardiness. So actually, Dr J, you ARE to blame!! (Or maybe the Ts are!).
We're not going to have time to start/finish any longer I think (oh the joys of parenthood/oncall/cats)
I think Jon's point of Pathfinder is a slow high mechanics system is valid (sniff, that'll probably mean no GURPS too!), so maybe we just need to play faster less rules intensive ones (and I know where my Dream Park rules are, yahoo!).
Though I for one DO like Roll20 as a platform, but would be nice to see if using it more sparingly makes for a better game.
