Hmm. Very interesting opinion piece, and it did get me thinking.
My opinion? We'll see if any real change occurs. I'm not talking about a week, a month, a year from now. I'm talking five years, ten years, twenty years. Protests aren't new. This isn't new. The use of technology is new, but the bottleneck for change is the message. That's why it's easy to brush off the protesters, and why shortly after the protests end, it will be forgotten by many. It's why traditional media really isn't useful here. They're looking for the ratings, the soundbites, etc. Want to know more? Go online, don't watch mainstream news. The Media should simply inform, not try to entertain (and that's the problem with all the media channels and outlets).
That's not to say that it won't be significant in a historical sense. Will this change the minds, habits and motivations for those who will be influential in the years to come? Will this protest lead the way to future protests? The protests have already spread, and I'm sure that many who protest in years to come will look at this one as an example of how to do it "right". On everything else though? We'll see. Technology is only as useful as those who use it, and as any fan of science fiction knows, it can be used responsibly... or not so responsibly.
