X to Mastodon, Instagram to Pixelfed, WhatsApp to Matrix, Facebook to Friendica, YouTube to PeerTube, TikTok to Loops

Maybe for whatever reasons you don't want to join the main mastodon.social server.

How about setting up shop on mstdn.social? This a very well run instance with a great administrator and a very engaged user base. It's big enough now and can grow to meet your needs.

Instance: https://mstdn.social/about
Admin: @stux

It is located in the Netherlands with servers in the EU.

Talk to each other. Give it a shot. We, the world, need you to get on board public social media.
