del.icio.us provides you with a virtual inbox to which you can add any other users’ bookmark lists. You then have access to this inbox via RSS. So, for example, in my del.icio.us inbox I effectively have the feeds for blech, yoz, kellan, msippey and xurble all bundled into one big feed with each item having an associated dc:creator to tell me who created each entry.

The problem I have with this is that I use JabRSS for all my RSS and Atom needs, which does nothing with dc:creator at all, making it pretty much impossible for me to tell who posted which item.

I can smell a new Jabber-based aggregator in the air. 😉
