For a sense of perspective, Twitter has 106 million users in USA. 700 000 is 0.67% of that.
This is additional new users not total users. Growing by 0.67% of the user count of the largest microblogging platform in the world in a week is absolutely massive.
I think the poster wants to say it means not that many in the US are leaving twitter or looking for alternatives, contrary to what the headline suggests.
Perhaps. Overall Bluesky is massive already tho. Twitter has something like 220 million users with Bluesky being around 14 million. Having 6% of the user count of Twitter is already beyond critical mass for the average user. People will be able to satisfy their microblogging itch on bluesky which means they wont go back. It has all the drama, porn and politics that twitter had.
Also for a sense of perspective, Twitter is owned by a Trump salesman that lies about everything (including user numbers that affect ad revenue). I’ve seen Bluesky users mention that actual engagement with real people is already higher than Twitter. It definitely feels more “alive” to me as well.
Relevant video from PirateSoftware talking about the difference in engagement between them.
