Recently there have been two more PieFed instances created, which offer accounts to anyone who wants one:
Feddit.online is hosted in USA which should make it a little faster for people there. It also has a different topic structure at https://feddit.online/topics than PieFed.social has.

Yeah, sort of. The total number of subscriptions (by all users) determines the load caused by federation. If you subscribe to 200 communities then I subscribe to the same 200 the federation load will not increase.
So once an instance has more than a dozen users pretty much every community that exists will be subscribed to and adding more users will not increase federation load (but it would increase load caused by the UI)
