  • Good but some shows are colts (etc.) fan boy shows

    It’s not my podcast so can do what you want as publisher but some shows are just way too focused on colts. Football card podcast is like a bears colts show that gets tiresome. And really the explicit language is not really needed. Immaturity maybe.

  • Good pod but needs diversity

    Lots of good insightful card talk, but leans too heavily into Colts and WNBA. I understand that it’s the way you hobby, but as someone that doesn’t care about either it can be a drag. Shows how good it is though considering I’ve stuck through it despite the lack of connection I have to those spaces.

Talking Points

Recent interactions between the hosts and their guests.

Built for the Hobby: The AI Questions Collectors Are Asking
Q: Can AI go beyond task automation and solve problems we don't yet recognize, especially for relentless dealers?
AI can progressively anticipate needs by observing patterns and suggesting actions, potentially saving time and revealing hidden opportunities, but it must be implemented with care to preserve the hobby's human-centric enjoyment.
Built for the Hobby: The AI Questions Collectors Are Asking
Q: What is the real upside of AI for collectors focused on enjoyment and long-term meaning?
AI can enhance inventory management, provide deeper, more accessible information about players, enable gamification and treasure-hunt experiences, and automate repetitive tasks to free up time for collecting and social engagement.
Built for the Hobby: The AI Questions Collectors Are Asking
Q: How can dealers use AI to source smarter inventory and improve margins, especially for singles?
AI can help track trends, timing, and performance data to identify potential undersold opportunities, but the human element and market instincts remain important; AI should augment decision-making rather than replace it, and over-automation can reduce the hobby's fun.
Built for the Hobby: The AI Questions Collectors Are Asking
Q: How can we get AI to generate a card value from an image for high-end cards with low sales history?
AI can assist with research and data synthesis, but because rare cards lack large data pools, human judgment remains essential for valuation. Tools can streamline finding and consolidating information, yet provenance and scarcity drive ultimate values.
Passion to Profession: Building WeTheHobby — From Collector to CEO with Zach Stanley
Q: What are you planning for 2026 and beyond, and how will you take what you're building to the next level?
The focus is on scalability through systems, automations, and improved customer experiences, continuing to invest in content and entertainment, expanding live-event activations, and formalizing partnerships (e.g., with eBay Live) to elevate the overall experience for fans and collectors.
