No mention of Twitter, Facebook or Instagram? It seems obvious to me that that is where the blogs went. People don't create content so that people they don't know have something to do in their spare time, they do it for the recognition, and social acceptance. In other words; they do it for the likes. The blogs dried up because the audience's attention coalesced on the few sites and apps that people used the most. Blogs won't come back unless people read blogs, and people won't read blogs unless doing so it easier than Twitter and Facebook. They don't care about censorship, or even privacy (apparently), just the sweet sweet dopamine rush.
