Thanks for taking the time to review; it was very helpful. I've answered
your questions and/or clarified my comments.

That's what I meant.

No technical solution build into the markup.

Like the list of RFCs. And like the list of W3C's specs.

Something is added to the spec, or it's changed; How can a parser tell which
"version" the markup writer was using?

See earlier explainations by Joe Andrieu, S. Sriram, and Håkon Wium Lie.

The community is this mailing list, and Tantek recently wrote several times
that it wasn't a microformat unless it went through the community process.

Non-visible data. Only considers existing market, not potential markup.
Community process not interested in scaling. I could add more.

Multi-year processes that require HTML to change, for example.

Control of what gets considered a microformat.

For example, no ability to create a "wine" microformat and split off it's
own mailing list and working group where those not interested in wine don't
have to participate, and those only interested in wine don't have to
participate in the "art" microformat.

Creating client parsing implementations for major platforms is not a
required part of the process.

Duplication of "No Microformat registry", sorry.

However, a blogging aggregator/search engine is funding time spent my the
leads of the process, so there will inevitably be subtle biased towards
bloggers, even if they try not to because those are the use cases they
identify as having value. For example, use-cases which enable e-commerce
companies to exchange data with their vendors and suppliers is not on their

I'm referring to the fact that the process is designed to be broadly usable,
not for addressing vertical needs. Looking at the list of "specifications"
and "drafts", all are blog related or general purpose. Looking at the
"exploratory discussions", the vast majority are general purpose.
As a counter-example, assume that you opened the New York City yellow pages
and listed off every section. For each section, there's a potential vertical
format. The current process cannot handle that level of specificity, and
when I've proposed changing I've been told that that was not the vision for

Quoting from Tantek "...microformats do not try to alter people's publishing
behavior in an unnatural way..."

Let me rephrase that. "Constrained to enhancing use-cases currently
published on the web" (as opposed to use-cases for data planned to be
published on the web.)
