Wow, this is a great dashboard, exactly what I was looking for. I'm thrilled that it includes all the sites that are linked to my Google Account, not just the usual  suspects SU/SO/SF. Yay!

However, some feedback from me, located in Austria (Europe):

On **WinXP+IE7** at work, neither the comments nor the graph(s?) are displayed, just empty space instead. Might be a firewall or other local issue?

On my **iPhone 3G** (iOS 3.1.3, not iOS4 with HTML5), the comments and graphs also don't show but instead a red text "Error retrieving data." This is on cell data, nto on wifi, if that makes any difference.
