A nice overview of the evolution of Bluesky by Gergely Orosz and Elin Nilsson.

Bluesky is a decentralized social network which was born as an alternative to Twitter. It’s super interesting that for almost half a year Bluesky only had 2 engineers and even today the team behind the whole platform is rather small.

It’s also interesting that infrastructure wise they have started with AWS and Pulumi and eventually moved to their own equipment for cost savings.
