I think it'd be better to create an open-source platform to power one "subreddit" that can be hosted and deployed by the mods.

Then the content can be exported from reddit into each of those platforms.

The instances could be federated. Reddit users could redeem their account across the federated network by proving they control the same account on reddit (either send a message to a bot on reddit, or by generating a one-time password then posting its hash to reddit)
