Comments: 

Keeper was incredibly slow for me (Jen).  My internet connection in Hawaii was fine so I'm not sure what was going on, but it would take 30s-1 minute to load scripts or switch tabs. I even tried exiting out and back in a few times but it never made it beter.  It seemed to have gotten better by about the last 1.5 hours of the night at least!
