Firefox still has less than 10 percent of the browser-share globally, but on sites like Boing Boing, it's a clear majority (check out the present stats -- almost 46 percent Firefox/Moz versus 34 percent Explorer). This also seems like it's true in cosmopolitan cities like New York. At a guess, I'd say that a lot of the Explorer market share is in corporations where people are forced into Microsoft's browser by their IT departments. Link, Torrent Link (via Digg)
Update: Booksandlibretti sez, "The video was filmed in Washington Square Park, which is basically part of NYU's campus. Chances are good that the interviewed people were a lot more hip, with-it, and tech-savvy than the usual run of people even in New York. We saw a lot of students, but I'm guessing a large proportion of the adults were also affiliated with NYU as professors or as grad students."
"Other interesting info: NYU grad students are on strike (detailed on MeFi and lots of other places). In this video, you can hear their whistle, and at times you can see the inflatable union rat in front of the large red building (Bobst Library)."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
