I tried it, as I'm looking forward to MORE people using the fediverse.
However, I do not like anything about the app.
Your Home feed is just random posts by people - all served up via algorithm based on what others have liked.
It's basically the shitty part of Twitter's "For You" feed, except that is the ENTIRE Threads app. No timeline for those you follow, no lists, no trending, etc.
The move toward heavily curated feeds is what made me leave twitter a few years ago. Tweets no longer showed up in temporal sequence. Likes frequently became retweets, & my feed filled up with things that distant contacts were liking, which was often far outside my realm of interests. Following an account didn't guarantee that everything they posted would show up in my feed. These changes just cannot have been motivated by people who used and enjoyed twitter, they made the service objectively less relevant, less interesting, and in every way worse for the user.
That's what gives me hope & gets me excited about the fediverse, where, commercial services effectively get forked, & you can hang out in places with features that suit your tastes, populated with people who also value those features. I really like that. Overall it makes things fragmented, but, there are these cosy little niches that will only get better. I'm a noob to this whole thing but seems to me, as soon as a slick, easy to use global fediverse search engine is created, or something with that harmonizing effect comes along, this thing is going to go big.
