“As Mastodon becomes more popular, it’s important that Micro.blog stays true to its blogging roots and unique take on social media, rather than shifting to be a Twitter or Mastodon clone. We don’t need a monoculture with all apps looking exactly the same.”

Yeah, I know. I shoulda put a /s on that; my bad.
