Avoid interruptions by time-shifting them

Let me guess, you're discussing that article 90 seconds in the future with Rorschach.

This sounds exactly like Read It Later. I don't know what the differences are between the two, but it's an alternative if you're looking for something like this. Anyway, my experience with this sort of thing is that I never feel like reading all the momentarily-interesting things I discover when I come back to them later. I think that by putting it off, you place reading about an interesting idea into the "this is something you want to put off for later" mind category and it never gets read, or at least that's what it felt like in my experience.

Ah yes, that's an excellent idea (and an excellent way to phrase it - "time-shifting").

Occasionally though, you might miss something if you time-shift it. Sometimes, I don't time-shift my reading for fear that I might miss something (oftentimes it's an opportunity to comment on the article while people are still reading it, in hopes that someone else will comment on it). I sometimes reassure myself that email notifications will take care of that, but some services (reddit in particular) don't give email notifications to people (they have another button of showing who replied to your post, but not everyone reads that)
