How to use Bluesky?
Once invited, users create a login which is then represented by @username.bsky.social as well as a display name which appears more prominently in bold text. If you want, you can turn a domain name you own into your username – so, for example, TechCrunch’s Darrell Etherington is known on Bluesky as @etherington.com.
The app itself works a bit like a simple Twitter, where you can click a plus button to create a 256-character post, which can also include photos. It is possible to reply to the posts themselves, retweet them, like them and, from a three-dot menu, report them, share them via the iOS share sheet with other applications or copy them as text.
You can find and follow other people, then view their updates in your “Home” timeline. Previously, the Bluesky app featured popular posts in a “What’s Hot” feed. This feed has since been replaced by an algorithmic feed and personalized “Discovery” flow featuring more than just trending content.
There’s also a “Discover” tab at the bottom center of the app navigation, which offers more “who to follow” suggestions and a steady stream of recently released Bluesky updates.
