The visual presentation is an "affordance" that tells users that
clicking on it
navigates. Without the blue underline, you are back to the mystery
meat navigation.
I certainly agree that the interface for interacting with
microformats in the context of the page would be considerably easier
to use with a visual affordance, but we should probably leave these
visual affordances (buttons, etc) up to the Web designer. If Firefox
were to proactively detect microformats and then modify the
appearance of the page, that is a line that Web browsers usually
don't cross.
Of course we have certainly considered doing this, here is a pretty
complete list of all of our design mockups that people might find
interesting:

We are still in the design phase for this feature, and looking for
lots of feedback and ideas. Changing the mouse cursor is currently
my favorite design, but we are completely open to new ideas.

I was thinking about this, and I wonder -- how did people learn the
behavior that you can click on a blue, underlined piece of
text? Think
about a pre-web world where nobody knew what hypertext was. People
needed to figure out somehow that you could click on links to make
them activate.
Enter, the hand cursor. If you think about it, it tells you nothing
about what's actually going to happen when you click -- instead, it
looks like someone about to click the mouse, so I suppose it's
inviting for people to mimic the gesture? This still doesn't answer
the question of how people would discover this. My guess is that
people scan the page with their mouse as they read. I know I do that
sometimes. Anyone have actual evidence?
Perhaps we don't need to worry about discoverability of microformats
further than just changing the cursor, after all.
Blue hyperlinks are an idiom, which, once learned, was easy to
understand.
However, they are far more than just the hover effect on the cursor.
They are /also/ blue and underlined.
Let's not under value the importance of that. The visual
presentation is an "affordance" that tells users that clicking on it
navigates. Without the blue underline, you are back to the mystery
meat navigation. Even today, if the text isn't blue underlined,
it better have some other affordance for me to understand it's a link.
IMO, cursor effects should /support/ affordance, rather than being
the primary indicator. The visual presentation should show that
something special happens and then the cursor effect confirms it.
My gut instinct for Firefox is that we probably need three steps
(1) an RSS-like microformats indicator (2) a way to "activate" uF
and (3) a way for users to then interact with said uF. We might
need offer multiple options for (2) and (3), we should certainly
consider several.
I like highlighting on a page, but that can be annoying and
certainly hard to control from the HTML designers perspective. But it
could be a glyph appearing near the "corner" of a uF rather than a
full "highlight" effect around the uF container. Clicking on the
glyph or the highlighted section then lets the user interact with
the uF in some way. Unfortunately, this messes with the design
and potentially puts the user in weird-mode where clicks do
"abnormal" things compared to the non-uF highlighted mode (normal web
interaction).
I think I prefer the idea of populating a list in a pop-up or
sidebar window with all of the uF available on the page. This avoids
the problem of design-clash and provides an obvious place for a
variety of interaction capabilities, like a right-clight to select
an application to send the uF to.
