Looking at my current open tabs, most of them are dense "boring" reading material like scientific papers (or reddit/HN discussions of them.) I feel they are important to read but don't feel motivated to do so ever.
I've never gotten to 100 tabs before. For entirely practical reasons, that Chrome can't handle it. It runs out of memory and grinds my computer to a halt. So I had to triage away the least important tabs and bookmark them or force myself to read them, just to keep my computer running. I just starting using firefox though, which is not helping this bad habit.
