As I'd posted this poll a week or so back, general direct-dialed telephony, a/k/a PSTN (public switched telephone networks) seem to be in trouble.

@dredmorbius same :) I currently blog on an ancient Wordpress fork hosted by #CoActivate.org, but I'm keen to transition to something that interacts with the #fediverse, as well as publishing to the web. I've considered using apps that allow long form posts and speak a number of federation standards. Eg #Friendica (#OStatus, #Diaspora, #ActivityPub) or #Hubzilla (all those plus #Zot). I'm also watching the tech deployed for @blog (WP + plugins).
