🌴146. The rise of vibe marketing and the fall of LinkedIn?

Happy Monday! Today I’m riffing on a recent episode of Greg Isenberg’s Startup Ideas podcast that had my brain buzzing. I love how freely Greg and his guests share what they’re experimenting with—this time, it was all about using AI agents to automate “vibe marketing.”

Basically, it’s like this: You prompt an agent to research top-performing content, write posts in your voice (as a conversion copywriter, no less!), and publish across platforms like LinkedIn or X… completely hands-off. Sounds wild, right?

While I’m intrigued by the idea (and I’ll be testing it this week), I’m also skeptical—especially when I think about how LinkedIn is feeling lately. Honestly? It’s been a slurry of soulless AI content. Automated comments. Robotic replies. And while it has been the best platform for my brand, I’m spending less and less time there.

Instead, I’m gravitating towards Substack. It just feels more real, more human. Like there’s still you behind the words.

I also talk about:

• How these AI workflows could help with book research and market positioning
• Whether books still hold their magic (spoiler: they kind of do)
• Why building an audience still matters—even if you have an AI army
• How I’m thinking about testing ideas on different platforms, and staying true to my voice

It’s a bit of a brain-dump episode, but hey—that’s what Leanne on Demand is all about.

Let me know what you think. Would you hand your content over to the bots?
