[Baypiggies] XFN, Web Frameworks and Google

[Alec Flett]

rel= has been around for ages! :)

This is one of the major ways google encourages people to decorate their
blogs to neutralize spammy comments:

But XFN was one of the first attempts to standardize the use of 'rel' for
anything semantic... the theory is/was that you could actually determine a
social graph from a set of blogs, if everyone just used rel= appropriately
in their blogrolls (Remember those?) - it still has some use here and there
(see technorati.com) but never really got widespread adoption...
