Perhaps we should start surveilling our citizens for signs of foment...
And anyone who agrees with this post is most likely not posting content to the internet with the same zeal to connect and share as they once had. I'm surprising myself by actually posting.
For me, the problem is that where most content on the Web was out on public pages, it now hides behind a Facebook etc. login screen. I don't use that service, so when I hit that login screen, I close the tab. After a while, it leaves you with a sick feeling.
The real problem is not that these older/better internet services aren't around anymore, but that most people don't look at every available option first, and then choose Facebook etc. They have learned that there is only Facebook and then commercial sites for buying/building things. They may as well not exist - so the argument that they are still there is mostly irrelevant.
As an example, the "young folks" (college/highschool age folks ) that I've convinced to use IRC with me have come around to my understanding, and feel basically the same way I do. But they wouldn't have known it was there, or how to use it. Back in the day, there was an incentive to learn about it. That incentive is gone - so it doesn't really matter if the services still exist or not.
Fundamentally, there may be no basis for anything.
