Medium CEO, Tony Stubblebine:

Today, Medium is launching a Mastodon instance at me.dm to help our authors, publications and readers find a home in the fediverse. Mastodon is an emerging force for good in social media and we are excited to join this community.

This strikes me as smart for Medium and a big vote of confidence for Mastodon and the entire concept of federated social networking. With Tumblr support (allegedly) coming as well, what’s next? Reddit?!
