Catodon's Threadiverse Catalog has been updated with the second wave of community suggestions. The Fediverse Observer has been added to the sources for discovering forums/communities, you can now search in specific servers, and easily select/deselect all options under Platforms and Servers. Thank you for the support and positive feedback!

It would be handy if you could log in there using your Fediverse account somehow and see who you’re already following. Otherwise, it would also be good to have the option to follow people directly from the page.
