Interesting Really Simple Discoverability

RSD seems like a very nice way to help user agents find the things that they need.

Add a bit of code:

[link rel="EditURI" type="application/rsd+xml" title="RSD" href="http://whereever the rsd.xml lives." /]

and compatible user agents can parse the XML file that you've pointed to, to find services, APIs, and other settings. Very nice.
