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:

code

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);
      });
})();
Clicking this bookmark will automatically copy a list of all your subscribed communities and format the links so that you can pop them in the search bar of another instance to subscribe to them from another account. It can only scrape what's on screen, so if your subscribed communities list is several pages long just click the bookmark for each page.
