If you ever needed proof that #Mastodon isn't “fragmented” or lives of isolated "islands" then just go ahead and post a cute picture with #CastOfMastodon or #caturday tags and watch what happens.
@ainmosni yeah, if I need to feel like I'm not tooting into the void I just share my cats XD
But it's also a great example of how federation reaches far, far more people than just your local cozy instance. Especially if you add a few relevant tags.
