X rival Bluesky ends invite requirement and opens sign-ups for all

Bluesky, one of several alternatives to Twitter that have gained popularity since Elon Musk bought the platform and changed its name to X, now no longer requires an invitation before a user can sign up.

Since its launch in 2019 by Twitter co-founder Jack Dorsey, Bluesky had said it was limiting the influx of new users so as not to overload its infrastructure, but announced on Tuesday it was opening sign-ups to all.
