What is the best way to open our presentation tomorrow?

Tomorrow, my team is giving our final presentation for our Tech Strategy course. Our subject is Fluther. What do you think would be the best way to open the presentation and why?

One of our ideas was to open it by asking a question to familiarize everyone with the site. If we did that, what kind of question should we ask—meta, course based, something chosen from an audience, something else entirely?

We’re very open to suggestions and presenting to an MBA class.
