Also, just to explain why I asked to conduct the interview over RealID - up to this point, most of my interviews have been with AddOn users and I have found that it has been helpful to interview people about AddOns in the environment in which they use them so that they can easily refer to their AddOns during the interview if they need to. So RealID has been my preferred method of communication, though, as I mentioned earlier, I have conducted interviews over other IM services and I'm more than willing to do so again.
