Adding XHTML Friends Network tags to your site

Jut another Web 2.1 feature - XFN - XHTML Friends Network tagging. It may grow up into the some kind of Friendorati network, it may not. I like that it inserts nice tiny pictures and shows some personal relations with people you writing about. Doing that why do not do it with some standard?

First - the CSS file (I think it belongs to the Phil Haack).

Second - the linking standard: <a class="xfnRelationship" rel="guru" style="position: relative;" title="Just an example" href="http://www.lazyloading.blogspot.com" />

And last but not least - nice images:

	friends	Friends as a monolithic group
	colleague, co-worker	Colleague who you have no idea about
	colleague-met	Colleague who you met (hurray!)
	friend	Friend (colleague in T-shirt)
	friend-met	Friend who you met
	guru	Perfect way to annoy people by marking them as minor geek celebrities (© Martin Fowler) and to point out humbly that you met The guy
	guru-met
	spouse	Spouse (that's right - handcuffs :)
	sweetheart	If you use "spouse" tag, I would avoid publishing this one
	sweetheart-met	Aggravating circumstance
	child	Surprisingly there is no picture for a child-met tag
	parent	I guess when Friendorati will unfold, families will use these tags to find their own
	XFN	This blog is XFN-compliant
