if you want to convine others here is a copyPasta that should work sometimes at least:
my copyPasta: wanna join the fediverse?

if not you can still look for alternatives on r/redditalternatives

Quick Quick start: open https://sh.itjust.works/ and consume the content. (could press on the all button next to the local button for more variety)

For a quicker start i suggest https://sub.rehab or https://browse.feddit.de/ to look out for communities that have your content.

If you wanna join lemmy please use a smaller instance like the recommondeed here: https://github.com/maltfield/awesome-lemmy-instances When you click on one you go directly to the content without the need for a log in.

Here you can roughly see how lemmy, Kbin, Beehaw and Mastodon are working: https://i.imgur.io/Hoc5dXU_d.webp?maxwidth=640&shape=thumb&fidelity=high
