As far as I can tell, the only reason old.reddit exists is to avoid the bad PR they’ll get from killing it. They seem to be trying to make things worse and worse, to lose the users through attrition, so the eventual shutdown is a non-event.

Also, maybe they learned something from Digg v4. That was a hard cut over, users hated it, but they had no way to revert and it killed the site. They’re probably trying to avoid that as well.

Do we know if the number of people using old reddit is significant enough?
