They form stacks of things that haven't been finished with yet. If I bookmark something in that state, it just falls off the end of my brain. In a tab it remains in my periphery.
I shall attempt to document what I am presently filling all those tabs with:
* Personal Gmail and Google Reader, along with a dozen or so links opened from them
* Several work-related OWA mailboxes and Google Apps mail and docs accounts
* 10 Hacker News discussions, including the one I'm making this comment in.
Normally there would be two for this discussion as I open the 'reply' link
in a new tab to not lose my place, but this tab was from a Notifo growl
* A couple dozen tabs are for music, TV, games, and films to investigate/pirate
* A dozen profiles of people to get in contact with on social networking sites
* Another dozen active threads on several phpBB forums I am a member of
* Several dozen tabs of product pages from manufacturers, alibaba, and ecommerce
sites for several physical projects I'm working on.
* A dozen tabs of research for software projects I'm working on
Depending on what I'm doing at any one time, any one of the things counted in
dozens could dominate. If you'd caught me during a RSS binge, there'd also ba a whole bunch of extra small windows each containing a single flash video embed, generated by the "Popout" functionality in Google Reader.
Of the tabs presently open, about half are new in the last 24 hours. Chrome's chrome://history/ page only lets me page back through 450 items chronologically, which is about a third of my average daily usage.
I've tried a number of tools to collect links in — bookmarks, social bookmarks, Google Docs, Google Wave, etc., but I always end up falling back to tabs because I'm already using them anyway! I'm currently giving the Chrome/GDocs bookmark syncing a shot for things that are 'out of mind'.
