Look, the six types of social media are: mail, instant chat, forum, blog, feed, and game. Twitter, Instagram, and Tiktok are feeds. Discord and Whatsapp are instant chat. Email is mail. Reddit is a forum that wants to be a feed, and it used to also have mail, but they got rid of it and replaced it with instant chat. Tumblr is both a blog and a feed, as is youtube. Any site with user pages is technically also a blog, but most such sites would rather be feeds. And then there’s games, most notably World of Warcraft, but also Halo and Minecraft and chess.com.
