What You Should Know When Joining Bluesky

Bluesky promises to rethink social media by focusing on openness and user control. But what does this actually mean for the millions of people joining the site?

November was a good month for alternatives to X. Many users hit their balking point after two years of controversial changes turned Twitter into X, a restrictive hub filled with misinformation and hate speech. Musk’s involvement in the U.S. presidential election was the last straw for many who are now looking for greener pastures.

Threads, the largest alternative, grew about 15% with 35 million new users. However, the most explosive growth came from Bluesky, seeing over 500% growth and a total user base of over 25 million users at the time of writing.

We’ve dug into the nerdy details of how Mastodon, Threads, and Bluesky compare, but given this recent momentum it’s important to clear up some questions for new Bluesky users, and what this new approach to the social web really means for how you connect with people online.

Note that Bluesky is still in an early stage, and many big changes are anticipated from the project. Answers here are accurate as of the time of writing, and will indicate the company’s future plans where possible.

Is Bluesky just another Twitter?

At face value the Bluesky app has a lot of similarities to Twitter prior to becoming X. That’s by design: the Bluesky team has prioritized making a drop-in replacement for 2022 Twitter, so everything from the layout, posting options, and even color scheme will feel familiar to users familiar with that site. 

While discussed in the context of decentralization, this experience is still very centralized like traditional social media, with a single platform controlled by one company, Bluesky PBLLC. However, a few aspirations from this company make it stand out: 

1. Prioritizing interoperability and community development: Other platforms frequently get this wrong, so this dedication to user empowerment and open source tooling is commendable. 
2. “Credible Exit” Decentralization: Bluesky the company wants Bluesky, the network, to be able to function even if the company is eliminated or ‘enshittified.’

The first difference is evident already from the wide variety of tools and apps on the network. From blocking certain content to highlighting communities you’re a part of, there are a lot of settings to make your feed yours— some of which we walked through here. You can also abandon Bluesky’s Twitter-style interface for an app like Firesky, which presents a stream of all Bluesky content. Other apps on the network can even be geared towards sharing audio, events, or work as a web forum, all using the same underlying AT protocol. This interoperable and experimental ecosystem parallels another based on the ActivityPub protocol, called “The Fediverse”, which connects Threads to Mastodon as well as many other decentralized apps which experiment with the functions of traditional social media sites.

That “credible exit” priority is less immediately visible, but explains some of the ways Bluesky looks different. The most visible difference is that usernames are domain names, with the default fo
