The shortened links aren't working properly; something weird with the URL shortener, I guess. I thought for a second it was the em-dashes in the URLs-- they seem to get stuck in there for reasons I cannot discern-- but it seems to not be working for all of them.
It's possible this is just me (I tried them on downforeveryoneorjustme and it said that they were up). I'm on OSX, updated Chrome, using Comcast, if that effects anything.
