I've weaned myself off Twitter except to check periodically for DMs, which is no small feat considering I used the site daily - many times a day - on and off for a decade and a half.
What's been the most remarkable for me is how little I actually miss it. If I'm being honest, Elon Musk taking over just accelerated Twitter's already occurring death spiral and gave me the impetus I needed to excise it out of my life altogether.
