Yeah, Reddit is currently a useful repository of some kinds of information and that won't instantly migrate. It's sad that even though every comment must be suspect when there can be any ulterior motive, it's still often more informative than browsing the general internet, not least because the results from Google are dominated by manipulative trash sites.

But I'd definitely apply pressure towards Lemmy - I intend to use it first and encourage people to come on over. Reddit brings nothing special to the party, it's just a simple but well conceived framework for people to interact (come to that, in 15 years has it improved in any way apart from 3rd party plugins and and apps?). The people are the thing, the platform just facilitates and protects the interactions (the latter will be the big challenge for Lemmy if it takes off).
