Yes. See [the microformats wiki][1] for a bunch of sites that publish
this microformat, and you can search the web's microformatted dates
using [Technorati's microformat search tool][2]. Momentum is building
for tools to aggregate and search microformatted data.

It's been discussed on the microformat-discuss list that using <abbr>
this way isn't less accessible in any practical sense. I can try to
dig it up if you're interested, but the point is moot - that is the
way the microformat is specified. I wasn't inventing anything new there.

Users using those databases are interested. Generating the right time
zone from a user-friendly syntax for dates is a challenge of my idea,
