Have you learned 758 things about home construction and interior design? Bookmarking certainly isn't learning. I should know; my collection of bookmarks contains countless papers, documentation, and tutorials, yet I've hardly glanced at most of them and the majority will remain in that state for eternity.
It’s been highly valuable. It taught me about undertones, color temperature, 60/30/10 rules, strengths and weaknesses of various countertop materials, load bearing, space planning, power delivery, millwork, lumber quality and cost, HVAC options, building code requirements, ceiling projections and light planning, fixture restoration, exposure to new vendors … should I go on? You bookmarked those once, surely you meant…
You could probably find the same information, most likely in more detail, in better context, and with improved searchability, from more "traditional" sources. Of course, if it's not clear what you want to know, the algorithm can certainly point you somewhere.
As for neglecting my bookmarks, I mean to do a lot of things ;) (I'll prune them this weekend, promise)
