I too use tabs as ad-hoc to-do list. In fact I have tab open right now that is open since at least 2011 as the relevant project is on kind of on back burner right now and the tab got in some way repurposed as a separator between stuff linked from HN/Twitter/FB/wherever and stuff that I explicitly searched for.
