One thing I think it is worth pointing out with regards this
discussion, is that there's a big difference between *identifying*
that a microformat is in use, and actually *processing* the

Identification is fairly straightforward, as these GM scripts have
demonstrated. But what's involved in processing? You need to parse the
information into a data structure, and then do something with that
data structure, which would probably take a lot more than 3-4 lines of
javascript, not to mention the design/creativity involved in doing
something useful with the data. But therein lies the potential...

You can post suggestions/requests for Greasemonkey scripts at:

If you have something microformats specific that you'd like to see a
Greasemonkey script to handle, please post it there.

As the wiki says, "smart people are listening".
