The next time you pay a visit to the Taza Chocolate Bar, you are surprised to discover a line, at least 20 people long, and an air of excitement.

The Taza staff was working furiously to stay ahead of the queued up customers.

The reason: Taza had posted an event on Facebook promoting a "limited batch of iced chocolate horchata and churros."

The deal: 2 horchatas (an iced beverage traditionally made with rice milk, vanilla, chocolate, and cinnamon) plus 5 mini churros for $15.

You can get a sense of the excitement, and the anticipation from the event's page on Facebook.

This first one was so popular they did three more: promoted here, here, and here. 

Taza fans, patiently waiting for their horchatas, did not notice the interactive display just inches from their elbows. Visions of horchatas and churros were dancing in their heads. 

On one of the event pages, one participant posted a picture of two young kids enjoying their horchatas and churros. Way in the back, if you look carefully, you can see your display, ignored. 

You understand: those horchatas look good. (The churros, honestly, are too fried dough for you.)

But standing there, you realize that if you want to continue your connectivity experiments, the Taza Chocolate Bar probably isn't the place. These people are here for extreme chocolate bars, chocolately drinks, and sugar-dusted, straightened-out donuts. 

Your sobering night at Cambridge Hackspace the previous night had demonstrated that many hardware hackers and technology sophisticates (roughly 50 percent) are uninterested in experimenting at the frontier of smartphone/IoT connectivity. 

So your target audience for this experiment has to be hungry for the tech edge, maybe to a fault.  

It's certainly too much to ask chocaholics, most of whom are likely in search of a low-blood-sugar fix, to switch gears into technology experimentation mode and engage in a challenging smartphone exercise with an incremental payoff.    

So you are not surprised, a few weeks later, when your display doesn't make the cut during a renovation of the Chocolate Bar. It was a good run, and a bracing reality check, but it isn't going anywhere. (And maybe the display was a victim of larger economic forces: within six months the entire Taza Chocolate Bar was closed down, to be replaced by a stripped-down coffee shop.)

The Taza team, sensitive to your disappointment, carefully dismantles the display and packs it in a large brown paper Taza shopping bag.  When you pick it up, you stock up on Wicked Dark chocolate bars (95% cacao) because you knew you wouldn't be stopping by as often. 

Your mourning period didn't last long. 

The next week, while visiting a friend in Boston's new Seaport "Innovation District," he points out a low-slung building in the midst of the fast-growing skyscrapers: District Hall. 

"It's the innovation community center," he says. "Free WiFi, meetups, that kind of thing."

That sounds like an opportunity. These could be your people.
