Last night, I took a short walk with my family before dinner. As we entered the park near our apartment, I was greeted by this sidewalk-chalk message from KC Kids, a local consignment shop for kids’ stuff. Sidewalk advertising ideas occasionally make their way into our brainstorms (yeah, we often step outside the traditional PR box), but we’ve never executed one. We’ve always decided to err on the side of caution, as the tactic is illegal — at least in New York, as Sony was recently reminded. However, some brands seem to get away with it: See last year’s campaign for Bravo by GoGORILLA Media.

In KC Kids’ case, I think it worked. The medium makes sense given the target audience. And the store is working to build a grassroots following in a small town. Unlike Sony’s situation (or the infamous Microsoft butterfly campaign that’s referenced in the article), there’s a slim chance anyone in Hoboken is going to come down on a small business for trying to create brand awareness this way. Besides, it’s raining as I type.

Next time, I hope they include a fun graphic element or clever copy. Adding a little entertainment value goes a long way in guerilla marketing.

Let me explain.

As a kid growing up in suburban New Jersey I’d heard about Space Farms and had always longed to visit. Friends who’d trekked to rural Sussex – which is 90 minutes from NYC – talked about the bears, snakes, tigers, and llamas that they’d seen and in some cases touched. (Llamas were and are my most favorite animal thanks to the book “Is Your Mama a Llama?”) Though I never actually made it to Space Farms as a child, I did get my chance when we won the business, as you can see. (That’s me + Tiny Tim.)

What we immediately learned about the brand is that my reaction’s not unique. Lots of people who grew up in the area know the name and have positive memories of the place, which was founded by Ralph and Elizabeth Space during the Great Depression, and is now being run by the fourth generation of family members.

In our work for Space Farms over the last couple months we’ve aimed to tap into these good feelings, and re-introduce old visitors to the attraction as adults so they’ll come back. We’re encouraging these folks and other influencers to spread the word about the unique rustic charm of the experience through traditional media and social media – Space Farms has an active Facebook page with thousands of followers and we’ve done targeted blogger outreach.

There are a lot of brands – Radio Flyer, Stride Rite, and Colorforms – that have strong connections to fans who grew up with them. It’s a good position to be in since those fans, who now have children of their own, are typically eager to share the experiences of their youth with their kids – a point made in this recent New York Times article.

The key for brands like these is they need to remind old loyalists they’re still around and make themselves relevant again – sometimes by embracing fans through new platforms, or by injecting new life into a vintage product. Colorforms, for example, is re-releasing an old favorite: a Michael Jackson dress up set; while Stride Rite has cultivated more than 90,000 fans on Facebook.

Nostalgia’s a strong motivator. As a child, I always wanted to kiss a llama. Check.

There’s a new video making its way around the Web today from a company called Grasshopper, which markets virtual phone systems for entrepreneurs. I found out about it when a friend of mine (who’s also a reporter at Fast Company) posted it on Facebook. I subsequently saw that it’s been featured on The Huffington Post.

In one day, the video has garnered nearly 200,000 views on YouTube. It seems well on its way to going viral. Why does it work? A spoof of Jay-Z and Alicia Key’s wildly popular “Empire State of Mind,” it pays tribute to the New Dork instead of New York. It’s well produced, clever and speaks directly to what makes entrepreneurs tick (in this case, I am their target audience).

This is the kind of “advertising” that people are responding to in 2010 – Grasshopper has shown through this video that they get the world I’m living in and they want to entertain me as much as they want to inform me. I may just give them a call.

Crass? Of course. Offensive? Surely some listeners thought so. Unexpected? Not so much if you’ve ever heard Silverman open her mouth before.

Chris Anderson, the TED organizer who invited Silverman to speak in the first place promptly tweeted about how “god-awful” she was. A Twitter-based ruckus between Anderson and Silverman featuring a bizarre side battle between Silverman and Steve Case (Case jumped in to defend Anderson) then ensued. The media hopped on the bandwagon shortly after and buzz and press coverage about the incident spread.

Love Silverman or hate her, my question is this: What was Anderson thinking when he invited her to speak in the first place? It sounds like she delivered material right in line with all the other material she usually delivers and he was taken aback?

The net-net from a communications standpoint seems to be a basic lesson: Do your homework before you hire a speaker. Keep “good” company, or at least know the company you keep.

We attended BlogHer in 2006 on behalf of our client WeightWatchers.com. The debate about the precarious relationship between trusted information sources and marketers with dollars aimed at garnering positive product reviews was percolating then and it’s raging now. (Incidentally, WeightWatchers.com was paying to attend the conference and exhibit, but they weren’t paying bloggers for posts.)

Days before this year’s conference kicked off, Elissa Camahort Page, the community’s co-founder, told AdAge that disclosure alone is insufficient. Her network is advocating that bloggers create a separate section of their blogs for reviews based on freebies, perks or outright compensation.

We’re members of the Word of Mouth Marketing Association and we’ve always been proponents of transparency. Camahort Page’s new proposal’s an interesting one. Ultimately though, which of the many proposals on the table is adopted doesn’t matter as much as continuing the lively dialogue. It’s important that there’s real forward movement on the establishment of best practices and policies – something both bloggers and marketers desperately need – especially since this world is evolving so quickly (next frontier: sponsored tweets).

Publishers, like mommy bloggers, have a right to monetize their work – how else will they survive and thrive? But they also need to retain their credibility and authenticity. We’re hopeful that as the industry moves towards consensus on these issues we’ll strike a satisfactory balance.
