I am Brazilian. It was a huge deal here. Now the national crazy is What’sApp, to the point that my cellphone plan caps my 4G Internet but allows people to keep using What’sApp. This bugs me a little because I use Telegram.
Anyway, Orkut was popular not only in Brazil but in BRIC. India, Russia and Brazil together count as a huge market. And yeah, it was very crappy but then, we’re all on Facebook that is equally crappy and even more shady.
