Now this is all pretty obvious, but the reason I decided to post it here is I've been using it for nearly a year and even though Pinboard seems much better, bmarks works pretty well for me, so maybe cheapskates like me could find this subset of features good enough too. Also, I really wanted to have a high-density view of my bookmarks (like Chrome/Firefox's explorers).
Regarding the ideal bookmarking solution, I understand the search approach, but IMO tags can be useful if you don't know exactly what you're looking for. For instance, here's [0] a list of designers/studios I often come back to when I need some inspiration and a a list of lists of films when I need something to watch [1]. You can definitely use metadata to simulate tags though. That's what I do for my music library.
And thanks! I really appreciate it!
