It was a real joy when I was a student doing extensive reading on topic(s), treating tabs as a reading list, since I didn't have enough stuff to do back then. Nowadays I find opening more than 10 tabs too counter-productive and distracting. What I'll do when it happens is using something like onetab to snapshot them all (with the hope of looking into it later, which never happens) and start fresh with the ONE thing I was supposed to focus at the time.
