I vaguely remember a video about history of weapons that goes like "rock, fast rock, pointy rock, (...) spicy rock dropped from big metal bird" (nuke) but I can't find it again. Does it ring a bell for anyone here?

One issue with the fediverse right now is that there are many redundant communities. Like !technology@beehaw.org, !technology@lemmy.ml, !technology@lemmy.world, etc all having essentially the same topic.

I think the easiest solution to this is to take reddit's multireddit feature, allowing users to create their own "technology" multi-community that includes all the popular technology communities from all the instances. Thanks to federation, the user could interact with this multi as if it was one big community. Perhaps a way to share the multi with others so that all the component communities get federate-mirrored to the new user's instance would be needed too.

I made a little thing to more easily move to another instance:

A way to quickly grab a list of your subscribed communities.

Go to your list of subscribed communities, /communities/listing_type/Subscribed/page/1 and create a bookmark with the following code as link:

javascript:(function() {
    const currentHostname = window.location.hostname;
    const table = document.getElementById('community_table');
    const anchorTags = table.getElementsByTagName('a');
    const communityUrls = [];

    for (let i = 0; i < anchorTags.length; i++) {
      const title = anchorTags[i].title.substring(1);
      const parts = title.split('@');
      const community = parts[0].trim();
      const domain = parts[1] ? parts[1].trim() : currentHostname;
      const communityUrl = `https://${domain}/c/${community}`;
      communityUrls.push(communityUrl);
    }

    const urlsText = communityUrls.join('\n');

    navigator.clipboard.writeText(urlsText)
      .then(() => {
        alert('Community URLs copied to clipboard!');
      })
      .catch((error) => {
        alert('Failed to copy Community URLs to clipboard:', error);
      });
})();
