"No one particular project should be considered a 'distributed social network'"
What? Something can be a distributed without being interoperable.
This article is humorously unbalanced. Sounds like someone venting. Even the counterpoint section is called "Perceived Advantages", haha.
Clearly, interoperability (or the lack thereof) can be taken to extremes; the hard part is finding the right balance. There's nothing in this article that helps with that.
