I think the article contains a little hyperbole, too. Leica were not the only manufacturer of cameras while there is only one Twitter. Blogging, Facebook, YouTube (and no doubt good-old email) have played their part in this but Twitter has a special place in getting information out and to journalists. There is no other technology that can spread grass roots information as widely or as quickly - especially to important recipients outside of the country. Important twitter messages travel amazing quickly and people seem to inherently pass them in the direction of high-follower and well-connected accounts. The fact the Egyptian Government turned the internet off and banned Al-Jazeera shows the weight that they placed on these media. And, while there is a mix of internet technologies being used in these revolutions, the term "internet Revolution" was already all used up.
