Last night our longtime client Post390 ended up in a conversation over Twitter with SNL vet and Boston-native Rachel Dratch.

She’s got a gig in a play up the street and had stopped by the restaurant for dinner. Afterward, she shared this from her Twitter account…

Guy Niel, Post390’s GM, picked up the thread on HootSuite, and the restaurant responded with this:

She said something nice in return, this time with a link to Post390’s Twitter account:

And the restaurant responded:

The whole thing took an hour. By morning, Post390’s banana cream pie was in the Boston Globe, and in New York Magazine popular food blog, Grub Street Boston.

There’s so much to be learned about how marketing has changed from this silly little exchange.

First, the spark that ignited this whole episode was banana cream pie worth talking about.  We say this all the time… but your product is your marketing. If it’s not good enough to inspire advocacy, measured by the creation of net promoters, you need to focus on that first. If it is, your marketing should flow organically from that.

Second, listening is no longer optional. There’s a conversation happening on the web that you care about. It might be about you. It’s probably about at least one of your competitors. It’s definitely about the problem your product solves, or you wouldn’t be selling enough of it to care.

Finally, the power of digital media lay in it’s potential to create scalable intimacy. A conversation between a local brand and a genuine celebrity took place in real-time last night, in front of the 90,000 people that followed both. That was inconceivable 10 years ago, but it’s how smart people do digital today.

Kudos to the good folks at Post390 for embracing this model so fully in such a short time. You guys earned what happened last night and this morning, and I’ll be stopping by for some banana cream pie myself a little later today.
