I'm wondering if instance subscriptions/cross-talk would be a neat feature to have in #Mastodon

I picture it like this: servers like @mstdn@social are great for general banter and have a broad reach, but are too chaotic for specialized discussion.

Specialized servers allow chatting w/ experts, but seem too limiting otherwise.

It'd be neat if you could subscribe to niche servers and post there on occasion (visible in the local timeline).

Best of both worlds.
