I don't have a Loops account, but check multiple sites for news and information, landing on the loops homepage several times. I haven't needed a login to see videos appear for some time.

If it's anything like the rest of the Fediverse applications, it's meant to give you a full chronological feed of people you subscribe to. While several of these sites seem to have a simple trending page, one of the themes of the Fediverse seems to be getting away from overly predatory algorithms and leaning into letting people curate their own feeds and interactions again.

It sounds a lot like a "be the change" situation. If you want to see other stuff, follow people you like instead of drinking from the hose. It's still a small site, so if you don't see the content you want, then make it or build the community there.

These sites can also have basic interoperability. I don't know if the Loops UI supports subscribing to people in other Fedi networks yet, but I've seen people say Loops videos have started trickling onto Mastodon.
