I continue to be impressed with Bluesky’s growth. From Last Week in the ATmosphere, covering the 10 million users milestone with 5.5 million monthly active users:

User retention after this new signup wave is also notably high, with daily active users peaking at 1.91 million, and staying at 1.57 million some two weeks later.

I hope the uppercase “AT” can be dropped over time, though. 🙂 Just “Atmosphere” is nice.
