Naz Hamid writes about how we should all keep social networks in their place; as methods of distribution rather than longterm means of connection or publication. He also contrasts that to how we could be thinking of our websites:
“If you care about your creativity, and what you make and bring into the world, I’d suggest having your own website. A place you can shape and change as often, or as little as you like.”
