I’m not sure this could get traction but I like the approach of using existing open standards.
So that's when I realized, if there's a widely used open standard for feeds, and another for profiles, why not join the two? By embedding an RSS/Atom feed URL in a vCard, it becomes a single file that has all the information needed to identify a person and follow their updates. Since it's a single file, it's easy to share it with others as well as store the vCards for all your connections locally.
You could have such a thing be entirely decentralized as well — just like blogs and their feeds are today.
