Ill likely be showing off some other topic specific instances in the future as well to give them more attention for people to use
What a great idea! After an admittedly small amount of fiddling, I've found my personal sweet spot in using "local" on topic specific instances instead of subscribing across instances. Restricting myself to subscriptions leaves too many interesting new communities unseen, but neither am I interested in subscribing to every passing interest. "All" is too much of a firehose for me.
I do still have a few subscriptions because there are some communities that never get enough traction to show in "local".
