Pinboard is a bookmarking website intended for people who want to reliably keep track of large numbers of links. Its goals are to be useful, fight bloat, keep things fast, and stay small. Social bookmarking for introverts. m.pinboard.

Pinboard is the most popular commercial alternative to Diigo.

Tagpacker is totally free, and provides a cleaner interface than Diigo for presenting bookmarks. I like it because it automatically grabs an image found in the page we bookmark, and when it fails, we can provide a link toward an image. There's also a feature that suggest tags, and autocomplete tags.
