I also have a bunch of 'things' that have been bookmarked for years: mostly movies and articles, some projects. This stockpiling has become tsundoku for more than books [1].
On one hand, divorcing myself from the initial impulse to consume or create something helps filter down to what I am and will be truly interested in. On the obvious other hand, the backlog grows to the point where I get paralyzed by so many options and the perfect ideas in my head that I end up not doing anything.
