I think that this is the most important thing, firstly. If Yedda could gain a tenth of the "hits" that Yahoo answers does, the money would come pouring in (with all the resultant problems that come with success). However, virtually no one knows about Yedda; it is unknown with the exception of word-of-mouth, as far as I know. If there were some way to finagle one's way onto TV, or any other media outlet, and the name were to get out there, boy...
Have you thought of trying to get on The Daily Show with Jon Stewart, on comedy central? Or, the Colbert Report? They feature a 5-10 minute mini-interview with authors, personalities, and assorted people with ideas. It would fit Jon Stewart's show (the co-founder of Yedda, and then a succinct description; I can see it now...)
Name recognition is the story.
