I generally don't rely that much on bookmarks any more. I find I can recall enough about a page that a few minutes searching on google is enough to find it again. So these sorts of mildly interesting pages don't get bookmarked.

Pages that I think might be useful for some task and that I'm unlikely to recall get placed into a comment on that task in trello. Overtime each task builds up a small online literature review.

Pages that fall somewhere in between get bookmarked but if they haven't made their way to trello by the time I next wipe my computer, they're gone.
