Is it possible to subscribe to an entire Lemmy instance?
I found the https://waveform.social/ instance while browsing for synthesizers communities, and the entire instance seems interesting to me and I'd like any content posted to that instance's local to appear in my subscribed list.
You could switch over to that instance and just use the local tab, then subscribe to whatever you had previously. Stuff from beehaw and other instances will still show in the All tab so you wouldn't be missing anything. That would allow any new communities on waveform to still show without manually following them. Apart from that I don't think there's a way without manually subbing to each one and going back to check for new ones every once and a while.
