BlueSky sits somewhere between X, Threads & Nostr, offering polish, decentralization, powerful moderation tools and most importantly a low Time-To-Value. The starter packs feature is brilliant.
X's algorithms, while antagonistic, drive a lot of interaction. I think there is a benefit to reading differing opinions. That or we're addicted to being pissed off.
BlueSky, in my opinion has a better chance of succeeding than Threads after the protest migration has ended. Threads is tarnished by being part of Meta's machinations.
Mastodon didn't stand a chance. For all the good intentions, its design is flawed and doesn't scale.
