What surprises and impresses me is that Usenet was huge: bigger than Slashdot or Hacker News, and bringing in a diversity of people (not just computer geeks). Perhaps the anti-spam made it difficult to welcome newcomers, and when the newcomers went elsewhere, other web forums grew up. What is the best way to balance safety and welcoming new people? I genuinely don't know, but would be interested to hear ideas. https://trends.google.com/trends/explore?date=all&q=%2Fm%2F059cs,%2Fm%2F06mt6,%2Fm%2F05zpmc6 https://trends.google.com/trends/explore?date=all&q=%2Fm%2F0...
