Did you listen to the video? It clearly states that they wrote a
specific hack for Craigslist, but that they expect this to work more
generically. Site-specific hacks don't scale to the Web. A solution that
scales will require a single parser, not site-specific parsers (though
site-specific parsers will likely be a transition path.)
The video's comments about microformats should make that clear.

You're confusing two issues. Craigslist doesn't want other *web sites*
redistributing their data. I doubt they would take issue with users
trying to process the data for their own private needs.
sites from reusing their data. They certainly don't make it too
difficult to screen-scrape, given their simple templates.

So, assuming you're right about Craigslist (and I think you're wrong, as
mentioned above), in your opinion, there won't be a reasonable number of
publishers who want to publish RDFa (or something like it?) Everyone
will just obscure their data so it's only human readable?
That's a rather limited view of the potential of the web. Do you not see
the value that's unleashed by tools like Ubiquity, and the incentive
that web sites will have to plug in?
