I spent the past week using Croissant to post identical toots to Mastodon, Bluesky, and Threads all at once.
Summary:
1. Mastodon: works as is—friends laugh at my dumb stuff, a few randos painfully explain my joke back to me
2. Bluesky: you get 2 likes or 200, no in-between.
3. Threads: my posts got 5 views or 5,000 views, no in-between. Also: context collapse as bad as 2018 Twitter with dozens of randos screaming at me how I'm wrong and I'm an asshole. Humorless.
