Calvin Yu has ported his Tails extension to work in Flock as a topbar. The extension, called Flocktails, reveals a micformats icon in the bottom right of the status bar to indicate the presence of hCards, hCalendars, hReviews and xFolk entries. This is the extension that I demoed at SXSW last week.
Take it for a spin and send bug reports to Calvin!

Thlis looks promising. Not entirely unrelated, I recently wrote an article about the existing start pages (like My Yahoo!), why I think they don’t have it right, and what start pages of tomorrow ought to look like. I think this could be related to where Flock is headed. I’ve also mocked up an image to explain my thinking.
It’s available here:

Sweet!
I’ve been using it since last night and I’ve decided that microformats are absolutley awesome. It didn’t really catch on with me till this extension. I gues the 7 stages of Microformats are pretty consistant with what I’m going through at the moment 😀
