This article reads to me as if Tumblr had renamed itself "Mastodon," as the cultures sound so similar. Both entail the notion of instances, Tumblr with subdomains (.tumblr.com) and Mastodon with users on one's own or another's instance (@*). I wonder if there's a sense of ownership entailed in that that leads to greater personal disclosure, which Twitter hasn't brought out.
