We should note that this Internet “entropy” isn’t random. The downward spiral always leads to the same place: racist, misogynist and homophobic slurs. That’s not really entropy — it’s a concerted attempt to impose order.
About a decade ago, I was briefly considered an expert (as much as anyone was) on social media. I gave some talks at influential conferences (not that I was influential), talked on BBC America radio once. That kind of thing.
I definitely leaned toward systems that would make it easy for people to create decentralized peer to peer conversations within trusted groups, and discourage open-ended commenting. For example, when Gary Hart became the first well-known politician to start blogging, I remember immediately leaving a comment (ironically) arguing that he shouldn't have open comments, that no good would come of it, and he should use trackbacks to other blogs, which is the way geeks thought (hoped) things were going in 2003.
Needless to say, when Twitter took off, it was a major move in the opposite direction. I guess my reaction was, "Apparently I don't know anything about what people want from social media, but there is no way this ends well," and I pretty much stopped talking about the subject.
I'm starting to feel like I was right all along.
