For years now I’ve done what I can to encourage use of other sites, but the fact remains that my specific community of friends and peers (many of whom have known one-another for over two decades now) have used twitter as a stomping ground since 2008 or so. It’s extremely difficult to establish that sort of intersection elsewhere, and it gets particularly ugly when folks’ livelihood and income are tied into the matter.
Having the main hub for communities torn apart because of one fool’s antics really, really sucks, and then I’m/we’re called garbage on the sites we try to establish on, for clinging to that lifeline. It’s all a frustrating feedback loop.
