They'd have a negative association with it, since the site didn't give them what they wanted. You don't want to start your first impression with a negative.
Possibly the majority of people would know what it was before clicking, because the search engine description would tell them. In that case they're just fulfilling their curiosity, which can only be good.
The 'move on' part doesn't exactly speak well for capturing new customers. Certainly not well enough that you'd sacrifice a better, more appropriate name?
Well, I guess the quality of the name is another point entirely, and the scheme might unravel there. :) I just thought it was an interesting idea. If the quora spike did come from Tron, I think it's at least interesting to consider engineering such an accident. It might be good, bad, or a wash, but IMO I think the bounces would be an overall positive. The name... that is another problem.
