If you aren't techy, you can still make your own Write Freely instance by using https://writefreely.host
You can connect existing WordPress blogs to the Fediverse by using this plugin:
It lets people on Mastodon etc follow your blog, comment, like and share its posts.
You can also find it in the plugins section of your WordPress blog, search for "ActivityPub" (all one word).
Discover & explore Mastodon with no ads and no surveillance. Publish anything you want on Mastodon: links, pictures, text, audio & video.
All on a platform that is community-owned and ad-free.
