From craignewmark@mastodon.social on Mastodon: . @ jeffjarvis is talking about his new book, The Gutenberg Parenthesis, at the Commonwealth Club in San Francisco on July 25. He's afraid of an empty audience. Can you sign up to come in person (but it's also streamed). Use the code JARVISCWC for $10 off. https://www. commonwealthclub.org/events/20 23-07-25/jeff-jarvis-age-print-and-internet-0
