As I've been seeing more and more posts about PDS and things like "lexicons" such as standard.site, I've been thinking more about how Bluesky is the main hub of all our our social data (for those left twitter and of course putting aside Mastodon for a moment).
This post gives a good high level overview of my own concerns about Bluesky being that hub, and though the post doesn't explain how they moved to Eurosky (and funnily enough then link to follow them on Bluesky) - it tries to demonstrate that it is possible to move data around.
I wonder how far we are from being able to self host and connect into the network to disseminate (I think this is the "relay" and I'm fairly sure this is far from trivial for a self-host job).
Still, one I'm keeping my eye on.
