Interesting. I seem to recall that the Getting Things Done time-management technique uses this very approach to help weed out unnecessary work (reading). The idea is that if the article is safely bookmarked, there's no longer any worry that we might loose track of something important yet (as you experienced) most of what gets bookmarked can be safely discarded without reading at all, saving time. So in the GTD context this "bug" is a "feature".
