I’ve been playing around with Joshua Schachter’s “social bookmarks manager.” It’s a browser-based bookmark service. It’s social because your bookmarks are stored on a central server, where not only you, but others can see them, and even copy individual bookmarks, with a single click, to their own collection of bookmarks. In addition, bookmarks are tracked so that you can see how many others have marked a particular page, and who they are. You can even subscribe to another person’s list of bookmarks.

Once you register for a free account, you can drag customized bookmarklets to your web browser’s toolbar. Whenever you find a useful site you use the bookmarklet to add it to your collection of bookmarks on the server. The URL is copied automatically to a simple fill-in-the-blank form that allows you to add a short description, and a single-world category or “tag” so that you can keep your bookmarks neatly organized. You have your own “page” on the server, with a static URL (in other words, a permanent address) and there’s even an automatically generated RSS feed for each person’s bookmarks page.

Why, you ask, would you want to share your bookmarks?

  • Your bookmarks are available from any computer, any browser.
  • You can benefit from what I think of as open source data verification—you can see how popular a particular site is, and who likes it—often a good indication about the quality of content.

In part because of the API, there are already a number of interesting add-ons from other developers. Brad Choate offers some helpful tips for users, rather than developers. I quite like Buzz Andersen’s, a Mac OS X client for using Another user has posted an AppleScript for posting to from Ranchero Software’s NetNewsWire. is pre-alpha right now, so while I encourage you to play with, make sure you backup your bookmarks. Wolf Rentzsch has some suggestions about here. Christina Zeeh has written delicious2safari, a Mac OS X client for importing bookmarks into Safari. There’s even a Java version of in development.

I’m especially intrigued, as my XBEL post makes clear, with the instructional possibilities of bookmarks. I often teach students and faculty to make annotated lists of bookmarks, creating a URL bibliography. Faculty often have lists of web pages they want students to use, but don’t know how to present or “publish” them. I see something like offering a lot of potential for “knowledge sharing,” to use the current jargon. If you want, you can see my bookmarks here, or subscribe to my bookmarks RSS feed
