What are the coordination costs of each author finding and agreeing to
use the same class values? Those costs are cheapest when the
specifications are centralized (e.g. microformats.org) but doesn't that
centralization act as a bottleneck to development? To get this kind of
coordination the authors have to wait until the appropriate
specification has been agreed.
I think there are similarities here with the coordination costs of
something like Xanadu (which required cooperation between parties to
form links) and the WWW (which doesn't, I can link to Google without
them linking to me). It was the elimination of coordination costs that
allowed authors to work independently and allowed the exponential growth
of the web.

Ian,
I understand what you're saying about letting authors write their
markup freely as opposed to bottlnecking the process. The trouble with
that however, is the ensuing chaos that emerges when you want to do
anything useful with the data being generated by those very same
authors.
What I think your contrast of microformats' bottleneck with the web's
free growth is missing is the notion that there indeed /was/ a
"bottleneck" in the development of the web in the form of Tim
Berners-Lee. It's just that it was all up front and not distributed
throughout its growth. When he invented HTML, he did the same kind of
work we're trying to do with microformats, but he did it by himself
and presented it to the community as a fait-accompli.
I believe that the growth of any data format requires some agreed upon
standard for its consumers to use. Otherwise, how can you ensure
reliable consumption of the information if you don't have any idea
what you're going to get? It's like parsing XML from an unknown source
without a schema.
If you want the benefit from the fruit of microformats, you need to
pay the cost of developing it. Besides, it's like the old adage goes,
nothing worth having comes easily.
Cheers,
A.
