I’ve used most of the options for this and regardless of the tool I do a terrible job of actually coming back and reading anything in them. Instapaper would probably be my vote for the one I used the most though, connected to my kindle it was nice when I used to travel and could catch up on stuff on the plane. These days I use Inoreader for consuming feeds and it also has a good read later function.

We did a Mexican vacation several years ago and everyone in our tour group would surround and excitedly take pictures of iguanas. The local tour guides would laugh and talk about how that always happens and how they were like squirrels to them.
