Went to Mastodon after Twitter got bought by Elon. Don't really care for the whole "He's a Nazi" stuff, mainly intrigued that corporate-free social media even existed. I was attracted by the no ad policy 😜 Since then I wouldn't say I was e erywhere, but I have embraced #IndieWeb principles by making sure I was on platforms I can easily switch from. For eg, moved my website from Squarespace to WordPress.com cos it can connect with the Fediverse. (comments on my Mastodon can appear on the related blog post for eg).
In the future it is said that WordPress and Tumblr will connect to Activity Pub. Still waiting 😆
Haha dang. I am not great with git yet, still learning. But maybe we can sort of keep an ever expanding list that people can add to. What platform is good for that?
