If you move everything to Lemmy, that won't happen much and as a result fewer people will join the community that don't already know about it somehow.
Cold start problem: initially the new community has no content archive and only a few users, most people are lazy, it takes time to relearn the ui and set up subscriptions(there is no good way to export/import subscriptions and saved posts)
Transfer of moderation: some people are going to take the opportunity to seize ownership of the new community, and the community will split up
Discoverability: reddit gets a lot of user traffic from google since google search quality has gone down and people add site:reddit.com to their search
We need a new form of social media where users and communities can easily export their content and data. A reddit clone with a similar UI is not enough.
Why not a reddit clone with the API data and some sort of claim for accounts via proof of ownership? Just make them comment a special string on reddit to claim your account on the new clone. Clone content and subreddits of the last X days. Shouldn't be toooo hard. Maybe use the reddit links for images and video for the first POC until you can serve them yourself.
Moderators could claim their subreddits, people dont lose too much - maybe also migrate your subreddit subscriptions.
Sounds like a 1 month job for a good team.
If a site allowed imports how would it work? It could work for all of a user's top level tweets, but for something with threads like reddit I don't see any solution.
the human internet is probably doomed. long live the llm generated internet
oh which gives me an idea: fake users as a service: using llm to generate comments for reddit after the dark
I cannot imagine, that this is not already being offered/in use.
