Yesterday, I thought I'd take crack at giving Mastodon - https://joinmastodon.org/ another try. Two quick tips for Twitter users:
1) Install Birdsite - https://gitlab.com/pmorinerie/birdsite so you can cross post to Twitter & Mastodon
2) Use Twidere - https://play.google.com/store/apps/details?id=org.mariotaku.twidere&hl=en_US&gl=US so you can see both your Twitter feed and Mastodon feed mixed in together
At least for me, this is a good transitionary step.
Liberdon is a Mastodon instance for libertarians, ancaps, anarchists, voluntaryists, agorists, etc to sound off without fear of reprisal from jack or zuck. It was created in the wake of the Great Twitter Cullings of 2018, when a number of prominent libertarian accounts were suspended or banned.
