I’ve always found that some instances being self described topic based has often caused confusion as well.

Have seen people create 3 or 4 accounts, a general, a food one, a Foss one, and a literature one.

On the flip side have seen people get analysis paralysis when deciding on an instance then just hedge and go for the big one.

On top of that, its very difficult at a glance to figure out which servers are like yours and are in for the long haul. There’s no real solution to that really other than how the instances present themselves.
