The move Twitter -> Mastodon reminds me of the move Matlab -> Python. I like Matlab, but Python makes more sense. So, I just signed up to pay a small monthly amount to Mastodon (info at
https://mastodon.social/about). Not super clear if the funds go to my "instance" (mastodon.social) or to Mastodon in general (if such a thing exists?), because this fediverse thing is, hmm, complicated. But it seems worth it. As someone else nicely put it, I'd rather be the customer than the product.
