Daniel, your English is excellent though a bit unclear in places. I'll try a response but let me know if I'm not answering your questions.

You have your own website and domain name, which makes you a part of the IndieWeb. I see you've also got Webmention set up, you your post sent me a notification and I've obviously received it. Since the Webmention Plugin handles sending the notifications, you do not need to manually put your URL into my site's response box and click "Ping me". I'll look into the error you reported seeing on Twitter.

Having an IndieWeb site doesn't automatically mean you're part of the micro.blog community. Since you've already got a domain name and hosting set up, you can sign up for a free micro.blog account and set it up to syndicate your content into it via RSS (or other means). Once set up, you can use micro.blog as a feed reader as well as to interact with others on the service. Since you've got Webmentions set up on your site, any replies to your content that happen on micro.blog will be sent to your website automatically.

Finally in relation to your question about the link menu on my homepage, most of the links are created as archives by the Post Kinds Plugin though some are created from WordPress core's Post Formats. I actually created the menu by manually writing out the HTML including the links and wrapping them with some CSS so they display on my site. Here's a gist of the HTML and the CSS code I used. I'll mention that the Post Kinds plugin now has a widget that does something relatively similar, an example of which is presently in my sidebar.

If you find it helpful, I've got a bunch of WordPress specific articles on IndieWeb (only in English): https://boffosocko.com/research/indieweb/.
