A book review exploring the history of Project Xanadu, Ted Nelson's pioneering but ultimately unsuccessful vision for a hypertext-based internet system that preceded and differed significantly from the World Wide Web. Longer summary

This book review traces the fascinating history of Project Xanadu, Ted Nelson's ambitious vision for a hypertext-based internet system that predated and rivaled the World Wide Web. Starting with Vannevar Bush's 1945 concept of the memex, through Doug Engelbart's groundbreaking demos, to Nelson's decades-long quest to build Xanadu, the post explores how this alternative vision for the internet - featuring bidirectional links, embedded content, and built-in attribution - ultimately failed to materialize despite its early start and innovative ideas. The review ends by questioning whether the simpler Web we got instead, built by Tim Berners-Lee, might have cost us something valuable in terms of how we connect and share information online.

Scott examines the potential future of online content filtering technology, considering its benefits, drawbacks, and societal implications. Longer summary

This post explores the future of online content filtering technology and its potential implications. Scott begins by describing existing tools like Tumblr Savior and Twitter blockbots, then speculates about more advanced AI-driven filtering systems. He considers three main possibilities: 1) everyone being better off by avoiding trolls, 2) people becoming overly sensitive by never encountering opposing views, and 3) a shift in discourse favoring the powerful over the powerless. The post concludes by suggesting that explicit filtering choices might lead to more thoughtful engagement with opposing views and the formation of separate communities with their own norms.
