WordPress Set-Up – Interdependent Thoughts

My current, October 2019, WP set-up is:

Theme: Sempress (with adaptations in a child theme I created)

Plugins:

Akismet Anti-Spam
Bridgy, for posting to Twitter from my site (and through the Brid.gy service getting back-feed from Twitter and Mastodon). I should be using Syndication Links as a replacement, but haven’t installed that yet.
Category to Pages WUD, to add categories to pages, which I use to make my 1-man ‘wiki’
Classic Editor, as some of the IndieWeb plugins don’t work with WordPress block structure, so I retain the old posting interface
IndieAuth
IndieWeb
Mastodon Autopost, to post to Mastodon from my site
Micropub, to allow me to post to my site using various clients such as Indigenous on my Android
Post Kinds, to create different types of postings, including likes, bookmarks etc.
Posted Today, to create ‘on this day in …’ lists of my older posts
Postie, to post on this site by sending an e-mail
Semantic-Linkbacks, to present mentions, likes etc from others in a nicer way
Simple Location, allows me to add locations to postings. Don’t actually use it.
Ultimate Category Excluder, allows me to keep specific categories on/off the front page, in/out the RSS feed, search or archive overviews. I use this a lot, creating different content streams
WebMention, to let other sites know I link to them, to hear from other sites they link to me
WebSub, not sure why I’m using it or what it does
Widget Context, to keep some widgets off single post pages as they interfere with correct microformats interpretation (machine readability)
Wordfence Security
Yarns, a microsub server. Not actively in use yet. I’m trying to set-up one of my existing WP test site as my microsub server. As I don’t want all my feed subscriptions in my live site’s WP database. So ideally I have the subscriptions in another site, while interacting with them from this site.
