All bluesky handles are domains, it’s their solution to decetnlized verification. For example Time Magazine has the handle @time.com, their CEO could have the handle @ceo.time.com. Its similar to email, you know an email from @nike.com is actually from Nike.

The default domain is bsky.social. Handles are subdomains on it (handle.bsky.social). If you have your own domain, you can make that your handle by adding a record to your DNS. This is in “Settings” -> “Change Handle” -> “I have my own domain”

Changing your handle to your own domain will make the bsky.social handle you originally set available again. If youre worried about that, wait for your next invite code and use that to hold the handle. 

After creating an account, you’ll start getting an invite code every 2 weeks.
(It’s not always exactly 2 weeks to the day, but it usually is.) 

Feeds/algorithms are decentralized. Anyone can create and publish a custom feed and they can be sheared like its a Spotify playlist. 

If youre interested in creating your own, the github template is here. The developer of Skyfeed.app (third party client) is also working on a visual generator, you can check it out on the client. 

Your bluesky account has its primary password (the password you set when creating the account), but it also has “App Passwords”. From what I understand, these are like sub-passwords to your account. They have less permissions than your primary password.

For example when logging into a 3rd party client, you’d want to use an “App Password” you’ve created rather than your primary. Same if you were a project with multiple people posting on the account. 

Its probably best practice to have a different one created for each person/3rd party client so if you have to remove access to one, you can do it without it affecting anyone/anything else connected.

App Passwords are randomly generated, they cant be changed or viewed after its set. If you lose one, just delete it and create a new one.

Its only photos right now.

Sort of, but not really. Its sort of a misconception that Bluesky is trying to replace Twitter. If Bluesky (the comapany) and their “AT protocol” are successful, then Twitter would be able to migrate to the decentralized network if they chose to.  These are, imo, the main distinctions to know (two of them are named “bluesky” so it can get confusing):

Bluesky (the company) – A team started by Twitter in 2019 to experiment with dementalized social networks. In 2021 it spun off into a Public Benefit LLC.

The AT Protocol – This is what Bluesky (the company) was formed to create. It is a framework for decentlized social networks. 

Bluesky (The App) – This is a proof of concept to test the AT Protocol.
