I work on the assumption that at least some of my behavior is irrational hoarding. It feels good to have acquired an item I can read later; the actual reading may be secondary.

If I never go back and read stuff I assume it's because it really isn't that important.

I've kept tabs open for a number of days, and then when I go and take a closer look I cannot recall why in the world I wanted to keep this tab open. Oh well; close it and move on.
