One issue I've had with read-it-later apps is that I end up accumulating far too many articles and never actually reading them. Now my approach is simple: if I see something I want to read, I either read it immediately or never.

There could be a better system (for me): a read-it-later app with a strict limit—say, 3 or 5 slots. If it's full and you add a new article, the oldest one gets automatically deleted to make room. That way, you always have something to read, but never feel overwhelmed by an endless backlog.

For me, this is just browser tabs. Modern browsers seem to do a good enough job with both persisting tab state between sessions and not expending tons of resources on idle tabs. So I just pop the article of interest up in a new tab and leave it there until I get back to it.

If you ever take a train (those where everyone has a seat) or flight, those are long hours perfect for reading.
