> Social media was about self expression and finding out where the party is

Exactly! My next project is going to be something like that. Based on the fediverse/Mastodon, but firstly about self-expression, connecting with real friends, meeting people. You curate your own home page, share what you want to share, you are invited to interact with strangers. No social media bs. Trying to capture the feeling of local / university social networks pre facebook, or the feeling of myspace.
