Unfortunately it seems bob has blocked mastodon.online so I have no way of recommending them as a follow 😞 (I would like to, but the block makes it technically impossible)
This is a brand new server run by the main developers of the project as a spin-off of mastodon.social It is not focused on any particular niche interest - everyone is welcome as long as you follow our code of conduct!
