That's not the point. Why rush the release when you know that historically Digg had problems with losing people because they severely botched a redesign?

Didn't Digg at one point purge their comments and there was a huge uproar? The new management shouldn't have went online without the migrated data, or at the very least, the user profiles.

They went with a minimally viable release and already have tons of feedback that, if they listen to it, will make Digg a great service again.
