“It’s basically a blogging platform that uses your ETH wallet as an account, and stores on Arweave. In that case, a blogger with an ETH wallet won’t need to register with Mirror, but just take the ETH wallet with him to Mirror and start blogging.

Since all articles are stored on Arweave, theoretically no one owns it and no one can censor it. Also, all articles are open and permissionless.

RSS3 creates a feed for any address, which would include a lot of interesting stuff — including, of course, Mirror blogs. Without RSS3, accessing Mirror’s articles can be very challenging for dApps.”
