Disagree with this take in general (growth is worthwhile if only to shift communications platforms in general to open and federated protocols) but I don't think Lemmy is quite where we need it to be in order to sustain a migration. Finding a good instance is still tough, the idea of federation isn't easy to grasp for a new user yet, and the UX is still hammering out bugs. (Big thanks to all the devs that already work on Lemmy and all those that shifted over with the Reddit exodus for driving it to new heights so rapidly.)

An ideal migration from my perspective would have them find instances that cater to their interests and views and would allow easy defederation if undesired. Also, more control for the end user in what communities they see on their feeds when going through discovery (new/hot/etc feeds).

With better user controls for self moderation and better distribution of users across multiple instances I think we can have our cake and eat it too: growth towards a free world of communications without bogging us down by dealing with the folks/attitudes we find repugnant.
