As a result, our instance https://lemmy.dbzer0.com/ got 625 new user registrations (of which 536 where accepted) in the past 24 hours! And the registrations are not abating even now. We still get like 10 new ones per hour!
I suspect this is probably the largest advertisement, for lemmy specifically, since the main reddit blackouts 1.5 years ago.
Have your own instances also seen an influx of new users?
Vscodium has been a very usable replacement for me. You lose some of the ms first party plugins (ssh being the most notable) but largely it just works otherwise.
I use this extension to get SSH support for VSCodium It works great!
