Cal Newport writes in The New Yorker:
Despite its advantages, however, I suspect that the IndieWeb will not succeed in replacing existing social-media platforms at their current scale. For one thing, the IndieWeb lacks the carefully engineered addictiveness that helped fuel the rise of services like Facebook, Twitter, and Instagram. This addictiveness has kept people returning to their devices even when they know there are better uses for their time; remove the addiction, and you might lose the users.
I have not tried out any new IndieWeb social media platform simply because I still can’t get rid of Facebook. Twitter I can control, but Facebook is still addictive. I do lots of cross-posting on here and Facebook as well.
