You want users. Hip, savvy, technology-wielding users. Users who know their way around the Twitter Interactions page. Users who belong to the theorized Creative Class.
Users who... work at coffee shops.
So you take your team there. You make sure you tell the barista "here," not "to go." You get the nice mugs. And then after you take the pictures, you use only the nicest Photoshop versions of Instagram filters.
Or, I don't know, maybe you just take a few screenshots and drop it into a Breezi template.
