I don't really wanna go into detail on this if I can avoid it but: we
use pubsub to publish stuff to our users from our backend (not zmq all
the way, but zmq pubsub in the backend part of it). The number of topics
all in all are linear to our total number of users, not a small set of
fixed topics. With a lot of users this adds up to a lot of
subscriptions. For example we publish stuff "your friend X did Y".

Hope that made some sense at least.
