I like octodon. It is a nice little place, and it's perfect for that thing where you want to tell someone something, but it's a general "someone", not a specific someone.
(as is the fediverse as a whole, i suppose, but one of the pluses of octodon and others like it is the size. It's relatively popular and lively, but it's still _small_.)
With that, I present: facebook is evil. https://thezvi.wordpress.com/2017/04/22/against-facebook/
