I know it's fun to be flippant or dismissive about Musk demolishing Twitter (and it is legitimately fun), but I am among those whose life trajectory was radically altered by Twitter, almost entirely for the best. I follow 272 people on Twitter, and there are another couple of hundred people who I don't follow but check in on, and hundreds more who I have discussions with often...and the loss of that social group is sad. I'm grateful that many of those folks are moving to Mastodon.
