Discussions on Bluesky starting to realize the inevitability of centralizing around one instance that comes with using a federation model.

Same applies to Nostr and it's blocklists and censorship tools in preparation. You own nothing on nostr and you are happy about it. Relays are instances dummy and already censor. Nostr is shit. Where were you during the time of biggest censorship on internet? Oh right on Twitter and FB. Fedi works. Nostr is shit already and soon the devs make the censorship here worse than Fediblock.
Relays feel like much less of a big deal than fedi instances. I find myself thinking of relays like "swarms" in that It seems clear to me fro. My use so far you need about a dozen or so of them at least for this place to work.
Got to admit I'm still bluesky curious, if only to see the other side of the Dorsey "A/B test"
