<![CDATA[XFN stands for XML Friends Network. You basically define human relationships between webpage authors by adding an extra atribute to links.
Well I decded to write a nice XFN crawler/search engine thingy. The crawler part works. I also decided to do a nice graphical representation of the links between sites.
Red is "crush", blue is "met" and green is "friend" (just three properties I picked at random).
