UB = ghost town?

[ZPinhead]

I started out playing on UB, mainly because I liked their user interface. As my game improved, I looked around at other sites and ended up play more at PP and PS. I hadn't played on UB for a year a so, but still had money over there so decided to play a few hands and see what was going on. I was stunned at what I found. Now, this was a weeknight, but only about 7pm PST. About a dozen tables at NL micro limits and probably 1 10 seat table at each limit level. What's going on? Has there really been that much of a shift of players?
