For me collecting bookmarks is part of a larger activity that involves any information I want to gather for use later on. Bookmarks is usually about assembling a reading list or collecting resources on a topic. I used to think the larger activity was note-taking, but I'm realizing that's not really it either. The activity is something very general like "collecting information". Collecting, notes, bookmarks, quotes, transactions, events, equations, etc.
I built a service to solve this problem [0], but I'm not sure how to communicate what it is. Does it collect and organize bookmarks, yes. But I also use it to track of my spending, do my budget, keep a work log, make financial projections, manage tasks, send myself reminders and digests of all the above content.
