I've been playing with This is a 'social bookmarking site' and duplicates the functionality of Linklog. Essentially, one can bookmark items and tag them. People can subscribe to tags, and bookmarks with tags you've subscribed to appear in your 'inbox'. I've only added a few links to date, but should be adding more over time. I think I'll work through linklog, and then make a decision about whether I maintain linklog or not.

Essentially every page has its own RSS feed, be that a page for an individual, a particular tag, or whatever.

One can even look at the tags made by a particular person.

I wonder if there is a way to define a 'community' of people who all share links?
