So, you know how Facebook is a corporation with a lot of spread-out servers that talk to a centralized database and algorithm that controls and manages all your posts, opaquely, for profit.
And so is Xwitter. And so is LinkedIn. And so is TikTok.
And so is BlueSky.
BlueSky's big claim is that they're "decentralized" with "no algorithm". And yeah, technically, ironically, everything's an algorithm, but I'm not well-actuallying that word. Their current default feed algorithm is not The Algorithm; it lets you see all the posts from all your friends and that's great. It also lets you block at will, and won't shove spam on your feed, or shadow-ban your friends' political posts. It's not evil (yet). It's fine.
But. It's not decentralized. #BlueSky is a centralized corporate app, running a theoretically-decentralized network protocol that currently has only one (1) active node on the network: BlueSky. The other minor members of the ATP network are just piggybacking on BlueSky's 13 million captive users for auth and reach.
It (allegedly?) uses #ATProtocol to pass messages between its edge nodes. But all its central features are still centralized, and the protocol allows "reach" to be centrally managed separately from "speech" (to enable centralized blocking, and goosing and filtering in various feeds), and the protocol isn't even fully implemented as designed.
For example, ATP allows for "DID"s for identity portability, so if you later want to switch to a hypothetical GreenSky competitor, you won't lose your followers and blocklist and post history.
But the actual BlueSky app does not implement DIDs. It's called "did-placeholder" on their github. It's a stub. It's TBD. It's not a feature, it's a feature request.
And guess who just bought a seat on BlueSky's board with a $15M Series A round? That's right, a crypto vulture named Blockchain Capital.
Their general partner Kinjal Shah -- whose cryptocurrency-fueled career has careened from Bitcoin to NFTs to DAOs to VC -- is now on the BlueSky board, and methinks the press release doth protest too much when it defensively claims, with just a pinky promise, "the Bluesky app and the AT Protocol do not use blockchains or cryptocurrency, and we will not hyperfinancialize the social experience (through tokens, crypto trading, NFTs, etc.)."
Go ahead and enjoy BlueSky. It's better than Facebook. It's easier than Mastodon. It's sassier than TikTok. It's not motherfucking Xitter. But it's not decentralized.
