It does indeed look like the social media landscape is fracturing into separate tribes. Whether this is good, who knows.
One quote from the article is this: “X for the rightwing and the raging; centrists and policy nerds on Bluesky; people who hate politics on Threads or Instagram; Gen Z on TikTok; boomers on Facebook”.
I feel like the thought that Twitter was ever a mass social platform for everyone is very journalist bias view. Facebook, Instagram and Reddit were already massive players before the Xtermination.
What they really mean is that they can’t create enough articles off of what someone said on Twitter.
