I recommend www.connectedy.com . Its byline is creating personal link libraries online. The concept is to change links from being like immovable doorways into being more like portable, handheld objects. Search engines show you all the links that you ask for, but they don't let you organize them your own way. Connectedy lets you collect links into your own personal library, share some or all of them, and categorize them in whatever way makes sense to you. Your shared links and categories get indexed in major search engines, so other web users may very well see your published pages (if you want them to).
There are several bookmarking managers out there, but I believe Connectedy is set apart by (a) its simplicity, (b) its integration with Google, and (c) the fact that the service is free AND no personal information is requested at all. What I am seeing on Connectedy is a community forming around sharing links and categorizing the web.
