When I used Google Reader, I didn't read everything together under one heading for that reason. I clicked on a feed, read the latest, and moved on to the next.

When I used Google Reader, I didn't read everything together under one heading for that reason. I clicked on a feed, read the latest, and moved on to the next. So on a slower feed I might always read everything, while on a very busy one I might just occasionally check in or read a little while and then mark the rest read. Now I use TT-RSS, which looks a lot like Google Reader did, but you run it on a local system. And I still read some feeds completely every day and let others pile up for weeks.
