I think you pretty much nail it. Active Tabs for news, mail, Youtube kind of things. Open Tab List ( That is why I really wish Apple would implement Tab Listing instead of Tab ScreenShots Overview ) For reading list and getting back into, I use Bookmark for something like long term memory. But part of the problem are the links no longer works.

I really like the idea someone on HN purpose sometimes ago. Where all your visited webpage ( excluding images ) are saved on your SSD, and you can basically search it back like your memory.
