Respectfully, I disagree. The display of the "title" attribute is entirely dependent on
browser implementation. Your statement is true enough for GUI browsers, but "title" is
invisible in text browsers, minimalist browsers (phones, PDAs), and any application that
scrapes HTML for the page content. I don't think there's anything in the HTML spec that
_requires_ conforming implementations to show or speak the value of a "title"

Again I disagree. It is not "good enough". It is "broken". The microformat use of <abbr>
is interfering with screen readers' use of the Web.
For every other aspect of microformats we insist that the behaviour of the microformat
follows usage found "in the wild". Here we have a documented case where the microformat
use of <abbr> does not match the use of screen readers "in the wild". It is likely that
screen reader users have a much larger use base than microformat users, and it is
unreasonable for the microformat community to expect the screen reader users and
developers to re-engineer their products to conform to an abitrary microformat standard,
especially now that Nelson Menezes has found a standards-compliant method to achieve the
same purpose without causing interference with screen readers.
We have here the opportunity to correct an oversight that's causing grief for a
