Bluesky is starting to look like an elaborate reboot of Mastodon with a fancy username redirect, but I'm guessing its technical aspects, while those are series of great achievements, were not the crucial part to its success so far; the part that worked was community building.

Nostr worked to some extent despite existence of Mastodon because Mastodon bodged that part. Mastodon took off because Twitter broke its community. Bluesky's successes is really making me feel that the first S of the abbreviation S.N.S. do stand for what it stands.
