WhiteWind is an atproto blog service that anyone with a Bluesky account can use for free, without providing any personal information. You can write blogs in Markdown syntax and publish them on the internet.
I found it interesting that there is already a blog that uses Bluesky's AT Protocol, although the disadvantage is that you need a Bluesky account to be able to make new entries to your personal blog.
If the resource intense relays will (most likely) only be hosted by big corps that can afford such servers, then what makes this proto better than any other centralised system? Killing the relays would kill the network.
