That's the way I've always overcome the problem of getting to bookmarks also. You give up a little real estate to keep the bookmarks bar visible, but it is a good way to organize things by subject matter, project, urgency, etc.
That being said, I'd love a configurable cache that would allow me to open a group of bookmarks to exactly where I left off on each page (or where I had frozen the data to keep a static record.)
I've not fleshed out his angle on this, but the first thing that came to mind was the gamification of every social interaction. "Ratio-ing" on TWIT comes to mind. There was a time when we measured threads by the level of social engagement (response) rather than like/share and it was a good thing to have hundreds of replies and sub-conversations.
Wrong. Compaq had much higher DOA and other defects in the mid 90s. They relied on customer institutional memory from the 80s when they really were the best.
Compaq is what ruined HP after they ruined themselves by going from a quality-focused builder to pulling parts out of the seconds and thirds bins to cut costs in the early-mid 90s. They absorbed DEC and ruined it then proceeded to infect HP (with Carly's help) with that culture. Not that HP was blameless either. I was done with HP when we received a $10k LH3 Netserver in '99 or '00 with both of its CPUs dangling inside the chassis from their fan cables. If my memory is right, they'd outsourced most of their building to Ingram Micro by that point.
