Blog post on metadata discovery

I've just read an excellent and very informative blog post [1] on the 
various approaches currently implemented or proposed for discovering 
metadata about a given resource. It makes specific mention of our 
proposals and compares them with a wide range of others. Its author, 
Eran Hammer-Lahav, is the chap behind XRDS [2] and OAuth [3] and I'm 
very much looking forward to meeting him later today at our outreach 
event at Yahoo.
