Yeah, basically. It's noteworthy that twitter is useful for this kind of thing. This was not some sort of foregone conclusion. When you first heard that people were twittering about all the inane stuff they do every 5 minutes, would you have thought it would also be useful for this?
It would be noteworthy if 10 other hard-to-control tools sprang up, too, which they probably will in time. The more communication tools people can use to carry out tactics against governments that try to cut off access to those tools, the better. I bet there are some other students in some other country struggling for democracy who think this is pretty noteworthy indeed, and will try to organize this way now.
