I always have around 8-15 tabs open, but 100? Dafuq. What could you conceivably have that you need to keep open all of those pages at once?
I believe Frumple has said in the past that he uses such a system in lieu of bookmarking things. Which somewhat makes sense, since I know personally that most of the things I bookmark I will most likely never look at again (I'm sometimes even conscious of this while bookmarking something, and yet I still do it).
Pretty much that, yeah. That and I'm usually actively reading, well... seven or eight things at once (it's pretty common for me to bounce between a dozen or so pieces of reading in a week, on top of the 1-3 I'll probably finished reading in entirety during the period), at a sort of minimum, plus probably manga/webcomics and LPs and keeping up with whatever web presence the game(s) I'm playing at the moment warrant and any school/life related stuff that needs doing and probably the weather or somethin'. I keep the browser busy, really.
... and anyway, it wasn't a hundred. A hundred is just the ones I
counted, and just the fanfiction related stuff. There was probably another 20-30 miscellaneous stuff that got sorted and closed, plus the fifty and a bit that got left open in the end. A good 150-200 tabs open is... normal. For me, anyway.
E: vvv It's the ctrl+tab/ctrl+mousewheel thing that does it for me, in Opera. Beyond that, I just... really don't like tab grouping. Opera's got that too, more or less, and for whatever reason it just doesn't sit right with me. I think I like having them all available at a single click, or something. Plus grouping actually tends to make it
harder for me to remember where things are, since it messes up stuff like "current fanfic N is besides LP Y".
