like "the machine that eats itself won't starve for your benefit"
anyway, i've logged onto "bluesky" and as far as i can tell, it's a "what if jack funded his own mastodon clone" give or take one big difference: aggregators. large third party 'for you' timelines that harvest and promote posts across instances. the other major difference is that there's vc cash behind it.
in other words, we have learned absolutely nothing from mastodon, and given how much bluesky reinvents, down to it's own RPC system, it doesn't look like anyone wants to learn to begin with. then again, we did set out to learn nothing from xmpp, smtp, and their ilk, so who can blame them.
"it's federated" is a nice way of saying "it's still centralised, just not in a way you're used to", control rests with the protocol, and the instance that commands a monopoly over the network.
much like openstack, or kubernetes, companies will jump on it, not out of a sense of user empowerment, but as way of collectively competing against the established players. established players might adopt it, if only to slow things down, and stall feature development, and whoever gets the largest userbase will withdraw from the network once they have a competitive advantage.
it's hard to say if bluesky, activitypub, or anything else will actually gain traction outside of niche spaces, but it really won't make a difference to me. i'll still be opening eight browser tabs and four electron apps to talk to my friends, as none of the federated networks talk to each other
it's a shame multi-protocol, multi-account applications went out of fashion last millenium
