Many-to-Many: The Innovator's Lemma
text: Seyed: Some would say that if you have more than one ordered method (i.e. authoritative classification mechanisms which can conflict, such as Yahoo! Directory vs DMOZ) then you have chaos. I believe that it's this to which Clay is referring.
Jay: Yes, the current structure of folksonomy is only freeform within tightly-defined edges. However, it's worth remembering that the entire existing folksonomy structure is a flimsy web consisting of a handful of implementations (and a fair amount of consensus) on top of the existing structure of the WWW, just like Yahoo!, DMOZ, WebRings and a billion other organisational methods.
One of the beauties of the web is that if one particular style of organisation doesn't suit you, it's very easy to build another. I think this is the main lesson here: not that folksonomies rule (Clay's been consistently saying they don't) but that they're a prime example of the kind of agile, makeshift classification of which we'll be seeing much more.
