IndieWeb: The Book (Chris Aldrich | BoffoSocko)

I’m going to write a book about the IndieWeb geared toward helping non-developers more easily own their online identities and content.

I know that I have provided my perspective already, but I have been doing a lot of thinking about it of late. There are so many elements that just feel so foreign. Take for example H-Cards.
I feel like I have been reading so much about them. As much as I think I get it, that it is a layer to a site that provides additional machine readable information, there is also a part of me that feels really lost. I am ok with that, but I feel that it is a point of confusion that needs to be resolved as the IndieWeb grows and develops. I assume when I retrieve the post properties in a ‘reply’ that this is calling on information located in the H-Cards? The question that I am left perplexed by is where exactly do I add all of this information?
Do I add it to the Theme Header file? If so, I presume that I would need to create a child theme. I must admit that this is an area that I still need to explore.
I noticed on your main site that you have your information in the margins on the right-hand side. Can it just be added to the HTML editor? What happens with a theme like ZenPress which does not have a space like that allocated on the front page? I presume that the H information needs to be on the front? Or can it be on an about page, like your Rel=”me” information.
Also, what happens in regards to posts and the h-entry? Just as I add a closing callout to my newsletter at the end of each post, partly inspired by Alan Levine, just with less humour, is it possible to bake the basic H information into each post?
Although there is plenty of information, I feel that much of it is written in a way that makes it a step learning curve for anyone trying to pick it up. Maybe there are prerequisite skills needed to engage in the IndieWeb. I am not sure, but that is certainly what I am wondering at the moment.
