Mastodon is terrible because it’s hard to join—unlike Bluesky, a social network that is hard to join, which is great.
Journalists are flocking to Bluesky, and not Mastodon because Bluesky allows retweets—which Mastodon doesn’t allow. Oh, and about hashtags, direct messages, and post edits not being available on Bluesky? Journalists don’t need them.
