I've been thinking about communities that have been meaningful to me.
1. USENET of the 80s (specifically talk.bizarre)
2. 90s rave scene, and the vrave online community
3. 90s SF web scene communities like Cyborganic +. spacebar + Thursday night dinner
4. Early(ish) days of Facebook, where I reconnected with old friends
5. Twitter, and connecting with like-minded people across the world.
Curious to see what the future brings!
