Over the last week or two I've heard of https://slug.com/ as well in fitting into the niche of a twitter alternative that takes a pro-liberty stand. https://www.minds.com/ is another and has been around for longer still.

I dont know yet of any good comparison of the pros and cons for each, and its annoying to have people you follow disperse and fragment out to different competing sites as twitter rots and stagnates, but that's the cost of innovation. And its far better that than being stuck on twitter. It mirrors the experience with thedonald.win in many ways.
