Usenet with full access to a big server was fun. With just NNTP access, it was diminished. 3 to 6 hops out in UUCP/WWIV/FIDOnet land it was a different animal. Still of use but high friction.
I assume you were taking something less than full feeds, because on a full feed reader server, just keeping up with the inode demands for all the messages was a challenge; grepping would have taken for-fucking-ever.
