As it turns out I do the exact same thing with both Reddit and Youtube. I don't click on links/videos, they both just get saved for later. This process takes maybe 10 minutes tops. When I have critical mass (every few days) I'll look back through what I've saved and read/watch maybe 1/3 of it, deleting most of the rest since I know I won't get to it or it isn't interesting any longer.

I think that the layout of these types of websites makes it hard to prioritize; we just instinctually click on the first interesting thing.
