I read with interest fellow Spinner Dave Morgan’s column about how software is destroying advertising agencies, but not the need for them. I do want to chime in on what’s happening in advertising, but I need a little more time to think about it.

What did catch my eye was a comment at the end by Harvard Business School professor Alvin Silk: “You can eliminate the middleman, but not his/her function.”

I think Dave and Alvin have put their collective thumbs on something that extends beyond our industry: the growing gap between people and platforms. I’ll use my current industry as an example – travel. It’s something we all do so we can all relate to it.

Platforms and software have definitely eaten this industry. In terms of travel destination planning, the 800-pound Gorilla is TripAdvisor. It’s impossible to overstate its importance to operators and business owners.  TripAdvisor almost single-handedly ushered in an era of do-it-yourself travel planning. For any destination in the world, we can now find the restaurants, accommodations, tours and attractions that are the favorites of other travellers. It allows us to both discover and filter while planning our next trip, something that was impossible 20 years ago, before TripAdvisor came along.

But for all its benefits, TripAdvisor also leaves some gaps.

The biggest gap in travel is what I’ve heard called the “Other Five.” I live in Canada’s wine country (yes, there is such a thing). Visitors to our valley – the Okanagan – generally come with 5 wineries they have planned to visit. The chances are very good that those wineries were selected with the help of TripAdvisor. But while they’re visiting, they also visit the “other five” – 5 wineries they discovered once they got to the destination. These discoveries depend on more traditional means – either word of mouth or sheer serendipity. And it’s often one of these “other five” that provide the truly memorable and authentic experiences.

That’s the problem with platforms like TripAdvisor, which are based on general popularity and algorithms. Technically, platforms should help you discover the long tail, but they don’t. Everything automatically defaults to the head of the curve. It’s the Matthew Effect applied to travel – advantage accumulates to those already blessed. We all want to see the same things – up to a point.

But then we want to explore the “other five” and that’s where we find the gap between platforms and people. We have been trained by Google not to look beyond the first page of online results. It’s actually worse than that. We don’t typically scan beyond the top five. But – by the very nature of ratings-based algorithms – that is always where you’ll find the “other five.” They languish in the middle of the results, sometimes taking years to bump up even a few spots. It’s why there’s still a market – and a rapidly expanding one at that – for a tour guided by an actual human. Humans can think beyond an algorithm, asking questions about what you like and pulling from their own experience to make very targeted and empathetic suggestions.

The problem with platforms is their preoccupation with scale. They feel they have to be all things to all people. I’ll call it Unicornitis – the obsession with gaining a massive valuation. They approach every potential market focused on how many users they can capture. By doing so, they have to target the lowest common denominator. The web thrives on scale and popularity; the rich get richer and the poor get poorer. Yes, there are niche players out there, but they’re very hard to find. They are the “other five” of the Internet, sitting on the third page of Google results.

This has almost nothing to do with advertising, but I think it’s the same phenomenon at work. As we rely more on software, we gain a false confidence that it replaces human-powered expertise. It doesn’t. And a lot of things can slip through the gap that’s created.
