As you look around for a new social media platform, I implore you, only use one that is a part of the World Wide Web. tl;dr avoid Hive and Post. If posts in a social media app do not have URLs that can be linked to and viewed in an unauthenticated browser, or if there is no way to make a new post from a browser, then that program is not a part of the World Wide Web in any meaningful way.
