I’ve just counted and I have 74 Firefox windows open… god knows how many tabs that is…

I think some really general-purpose communities like films or books are good to be one per large instance, as they’ll be busy enough to have plenty of content without them getting so big you have that Reddit thing where it feels pointless trying to contribute unless you’re early.

Smaller, more niche communities definitely are harmed by being spread out as they get too quiet to survive.
