Reading through the comments in this thread, it looks like the population is split in two groups. The first group considers "bookmarks" as a directory of often-visited sites, and needs a way to avoid typing their URLs every time. The second group intends "bookmarks" as a wish list for sites that might need a second (deeper) visit.

It may be time to find another metaphor for this second group: "postcards" might work better than "bookmarks".

the second group is why read-it-later services exist.
