I've just realized facebook have 5-6 IDs all tied together

1. Original email address
2. facebook.com/foo
3. facebook.com/UID
4. foo at facebook.com
5. graph.facebook.com/foo
6. graph.facebook.com/UID

This is very clever stuff, imho.  I think the FB graph is extremely
well organized, and possibly gives them a competitive advantage.
TimBL always says, 'give everything a URI and let them link to each
other'.  Facebook have done exactly that, and I think it's the design
model to follow.
