I just checked out Diigo and it looks pretty cool. It lets you annotate, share, and search your archived bookmarks which as far as I can tell, Pinboard doesn't do. On the other hand, Diigo only stores the HTML (like wget) and a screenshot, whereas Pinboard will store the CSS, Javascript, images, and embedded videos, similar to what right-click, Save As would do (minus the video?).
