A-priory you would expect a guy who went from emerald mines to riches to know more about making money than someone who dedicated his life to science.

But if Musk wanted to destroy Twitter could he have done so much more thoroughly? Cheaper probably.

FediScience has almost 1000 active users now. Other science servers are also exploding. Many people signing up now give as reason that they follow others leaving. I have seen several people claim there is more science action here than on Twitter.
