I think most of these still suffer from being descriptive. I believe it was Steph the Geek who pointed that out in the other thread. They aren't very catchy, and are almost more just talking points for a board meeting. I'm not saying I have any other great ideas just yet, but maybe a "None of the above" option would work so we can gauge interest in waiting for round 2 options.

I understand we're not necessarily a company trying to market a brand, but we are a community trying to show Ubercart's strengths to the kind of people who aren't necessarily in tune with open source software and development communities. But still... what if these brands used taglines like this...

McDonald's: Cheap, flavorful fast food
Nike: Shoes you can use
Burger King: Burgers under fire

Rather, they use tag lines unrelated to what they do that project a sense of how they want to be perceived...

McDonald's: I'm lovin' it
Nike: Just do it
Burger King: Have it your way

So, we're not necessarily trying to sell things like these companies, but it sounds like the goal is to evoke some sense of "Ubercart can do what you need, and it's for high rollers, too" without resorting to just using a brochure's talking points.
