Yeah it can definitely be confusing, especially because some people build their own websites, some want simple ways to get Wordpress functioning and micro.blog aims to be as close to 0 config as possible. So everything has different audiences 🙂 Feel free to ask me any questions you have as you try to figure out what you want to do. There is also a Slack community and IRC community for the IndieWeb where you can discussion questions and find answers: https://indieweb.org/discuss
What IndieAuth provider do you use? Micro.blog? IndieAuth.com? Known? Wordpress? That is an error which how your IndieAuth provider is verifying URLs and it’s missing part of the spec. I can reach out to the maintainer of whatever your provider is to help them update to the latest spec.
@manton I read http://help.micro.blog/2018/replies-and-mentions/ and am somehow conflicted, I'd like to own my replies too, and with normal IndieWeb I do, I have them in a special comments section: https://jeena.net/comments
But the FAQ says that when I use the app or web those comments get stored seperatelly and are not send to my blog. Is there a technical reason why that is? Couldn't they been send via MicroPub to my blog?
