There is an update on Reeder for iOS and Mac on it’s website.
Reeder for iPhone is being updated to use Feedbin, and can already use other services (like the self hosted Fever, but not on the iPad app, which still hasn’t been updated), and he is working on standalone RSS, but he plans on adding more services soon.
As for the Mac and iPad versions, they have both gone free as of now until he can come out with an update that includes all sharing and syncing services, which will be version 2.0.
I just want the iPad version to be updated, and may consider trying out Fever, since it is self hosted and will soon be able to work with Reeder. Hmm.
