I don't think it could happen today. Reddit has too much critical mass and the community is too diverse. Back then Digg was a smaller and more close-knit community of mostly techies that mostly agreed on the same things. There was a movement a few years ago where some Redditors tried to create a Reddit alternative called Voat, which ultimately failed.
