I think there will be more activity once they add more features. It’s very bare-bones right now. I honestly like the app, though, all things considered. I hate Facebook/Meta, but it’s been a nice app to just scroll through, and there’s been enough content to use it as a time killer. They desperately need a proper search feature and a trending page, though, especially if they ever hope to fully replace Twitter. Overall, I like it more than both Mastodon and Bluesky, because discoverability is so awful on Mastodon and Bluesky doesn’t have enough users and content because they haven’t gone public yet. And I very much like the idea and structure of Mastodon much more (with it being open source and federated), but the user experience has been so bad for me, with discoverability being the worst aspect of it.
I think the main method of discovery is through your network, and through your local instance. Federated timeline tends to be chaotic, but I definitely like reading my local timeline on my regional masto instance. But I believe that was the intention on the design, no 'trending', no algorithm, just the people you follow.
Yeah, I unironically like trending sections and algorithms, at least to some degree lol I understand the downsides of them, but I enjoy things being shown to me that I'll usually enjoy seeing. The YouTube algorithm for example, despite how finicky it can be to work with as a creator, is very good as a user, in my opinion.
