This would be lovely. Then once that functionality was working, we could create a Reddit-style front-page for new accounts that subscribed to a bunch of popular hashtags. That would really help to ease onboarding and make instances feel a bit less isolated.
I think I’m on Lemmy for the long haul - I like the fediverse decentralisation. The hardest part of Reddit to abandon will be the search results on Google, but perhaps we’ll see something similar with Lemmy in a few years if it picks up steam.
