"When Riley posts something on Facebook, there is almost always feedback. Riley’s friends often click an innocuous-looking ‘like’ button that serves as a low-cost, high-value social signal that reinforces Riley’s use of the platform. By contrast, Riley has no guarantee that sharing their thoughts on a personal blog would reach much of an audience at all."
This quote encapsulates the problem that the Indie-web movement has yet to fully resolve. While micro.blog is a great step in the right direction, it still doesn’t provide that immediacy of connection - and that endorphin hit of a ‘like’ or a ‘retweet’ that social media is able to provide.
I encourage you to read the rest of the article; it is well-written and effectively articulates the challenge.
