They all federate together, but each app shows at best what it was built for and simplifies the rest. A Mobilizon event seen from Mastodon shows up as a regular post: the details are there, but no way to interact with it directly. A PeerTube video shows up as a link, not a real player. To get the full experience, one account per network is still the usual path.</p><p>(2/4)</p>]]></description><link>https://citiverse.it/post/https://toot.fedilab.app/users/apps/statuses/116642738573271308</link><guid isPermaLink="true">https://citiverse.it/post/https://toot.fedilab.app/users/apps/statuses/116642738573271308</guid><dc:creator><![CDATA[apps@toot.fedilab.app]]></dc:creator><pubDate>Tue, 26 May 2026 20:22:23 GMT</pubDate></item></channel></rss>
