I'm hoping someone might be able to toss a link my way. I could swear that I've heard of a fair number of online bookmark tagging and sharing sites which also scanned through the bookmark collections on a regular basis, and then offered suggestions to individual users about new sites from people who shared a certain percentage of interests or stored bookmarks, moved up or down depending upon the popularity of the potential suggested link in question.
But, I'm not seeing anything like that anywhere. From those I've looked at, furl comes closest. But it's still nowhere near as automated as I was hoping to find. I really suspect that I'm just missing some feature in plain view on many of these sites. It seems like a fairly useful feature, and it's certainly not anything which would require much of a time investment to write. Even off the server, I'd assume a weekend would be enough time to put something like that together for a site like del.icio.us which has a fairly accessible interface library. But...I really don't want to give up a weekend if it's already sitting in some option menu somewhere. Any suggestions of social bookmarking sites which offer something like that?
