Timezones
Well everyone starts and ends blogathon at the same time, so we're all probably equally tired. The Sabbath schedule people start at a different time though. So the difference will just be how bright it is outside. I think we got a decent time, since 9AM is a good waking up time. Except we'll be all messed up when going to sleep all during Sunday. Then you won't be able to sleep Sunday night and you'll go to work tired on Monday and probably get fired. Or maybe just cause a major injury or mistake.
