+1 for bio and vcard and geo namespaces. All commonly used to extend 
foaf.

And not just in FOAF. Lots of people would like to be able to enter 
birthyear, or Birthday but not year. Social Network sites rarely allow 
this. And I suspect this is because the developers had a single field 
for birthday as an INT using the unix timestamp.

Much more likely to be oAuth as the consuming system is an application 
rather than a user.
