Excited to release Discourse, a tech forum for the modern era. discourse.cosign.co Today, the discourse in tech is either free for all (broadcast social networks) or completely private (group chats). There’s no midsize social network where a few thousand tech leaders talk to each other. We'll have a hybrid model. Some people will have access to post directly, and everyone else's posts will go through a queue. We'll start with ~5,000 white-listed people, and more people who post smart comments will be given direct access over time. Discourse is built off the @cosign graph and will be embedded into the platform. We’ve partnered with our favorite monitors to make sense of what’s happening in real time. P.S. True to form, I actually built a version of this a decade ago called @beondeckdaily, inspired by Hacker News.
