It's ok. Here are some of my thoughts:
- The lack of a web interface to browse Threads is frustrating, you can only view a specific thread someone has shared a link to before it forces you to download the app. - No following feed, so I've had to mute dozens of media/political/brand accounts that appear on the homepage. - No chronological feed is annoying. - You also can't search for keywords/hashtags. I primarily use twitter to receive real time commentary on events, so this is the biggest downside in my opinion.
Overall, Threads feels like a beta product that was rushed to release to take advantage of the rate limits implemented on Twitter. We'll see in a few months if Meta can follow through in building an app with the feature parity of Twitter.
