He mentions reddit and wikipedia, and they are some of the worse places on the net. Ideologically driven places, you ever question their narratives they'll start a witch hunt against you. Who's to say this couldn't happen on minds. When you get alot of people into one place it can create an echo chamber, but as long as they don't advocate safe spaces and let peoples ideas be challenged with debate the site could work. Also I would push keeping your identity anonomous, that won't stop people from signing up with their real name, but as long as the main focus be freedom of speech. I'll make an account, and check it out. I wonder how people will react if someone makes a page for white supremacy or something lool.
