Quick Books has taken the idea of marketing to a different level. Instead of having the marketing pin-heads telling you their latest corporate strapline, they're putting it out to the vote. You can see what they're proposing here. Personally, I think all of them are tacky but then I'm not a professional marketer.
Even so and choices apart, it's a great idea and one that will resonate with the community. What would your clients say for your strap - Dolittle Plunder & Grabbit perhaps?
