have you tried another client without the endless scroll? Also unfollow or mute everyone who isn't posting things you find real interesting (and also some that post interesting stuff but posts way too much, those I move out to a separate list which I review sometimes) :-)
I find having a manageable timeline a super useful tool to catch up on interesting or important news. But every now and then I notice that even with a old-fashioned timeline I spend too much time and I look over who I follow and cull people who post too things I forget the second I've scrolled past and instead keep the people who post well-thought-out things infrequently.
