If your situation is anything like mine, it goes much more like: "oh, neat; I'll look at that tonight" followed by a browser bounce, or something else becoming a bigger priority, lather, rinse, repeat.
There is so much great content -- both "empty calories" and otherwise -- that it is so easy to get buried under it. I came to HN to retrieve _one specific link_ and ended up with 7 new browser tabs open, counting this one.
