I'm fine with how active things are. The most popular community I run (!bluey@lemmy.world ~750 subscribers) is receiving at least a post per day, sometimes up to five.
If another "event" happens, I'm sure we will get busier, but things seem manageable for the two of us so far. I'm not opposed to more traffic, however.
Baseball is in mid-season right now and it appears each team sub has a bot posting game threads and live updates. American football will be starting up in a few weeks as well.
