X usage has declined as downloads of Threads have surged in recent weeks.
Data from two research firms and figures published by Musk and X suggest a deteriorating situation for X by some metrics. Musk has marketed it as the world’s “town square,” but in number of users it continues to lag far behind social media rivals that focus on video, such as Instagram and TikTok.
In February, X had 27 million daily active users of its mobile app in the U.S., down 18% from a year earlier, according to Sensor Tower, a market intelligence firm based in San Francisco. The U.S. user base has been flat or down every month since November 2022, the first full month of Musk’s owning the app, and in total it’s down 23% since then, Sensor Tower said.
Bluesky will be around as long as there's a company behind it. If it's not profitable, it'll cease to exist overnight. Activitypub will be around as long as people enjoy it, which is a lot more sustainable.
Mastodon is just one platform used to access the Fediverse. I agree, Mastodon might not be the hottest Fediverse microblogging app in a decade, but the Fediverse will certainly still be around. And that's what you should really care about.
Don't go to Mastodon specifically, just go to the Fediverse.
