I am an active user of Cohost, maintaining both a personal page as well as a ZZT specific page.
I can be readily found on the Mastodon instance Chitter.
I maintain YouTube accounts for ZZT posting and a personal one for anything else.
I maintain Twitch accounts for ZZT streaming and a personal one for anything else.
I still maintain a presence on Twitter for my ZZT account, though I log into it infrequently these days.
Note that I don't check my inbox all that often.
