I can keep up with mine - and I like to look at each one.

Actively follow the few, where I have no idea and want to know what others settle on.
Still waiting for iNat to bring us the promised way to manage notifications. One person has left iNat in despair at their deluge of notifications, which is sad.
If Bombus is ‘your problem’ you could proactively UNfollow each time you add an ID to the ones you don’t need to be notified of. Keeping notifications active for the few that you are interested in.
