Missed those. I found two, one with a search, one linked as similar to that:
https://www.theguardian.com/technology/2022/nov/08/mastodon-what-is-it-how-do-i-join-use-find-best-server-list-change-elon-musk-twitter-leaving-social-network-alternative
..the other is an article from April, 'Are people still there'.
Neither one takes a first-person view, as in "I signed up and did this with it". Even the first one is "you can sign up, if you want".
Today's Threads coverage is all but an advertisement, it's so positive.
I take your point, but only part way.
