To be more explicit, if someone is nominated here by other members but never shows interest by submitting an application, I think it is unlikely we will be considering them for a mod position. And if they submit a crappy application or a non-serious application, that's not going to help their chances much. I advise those who are serious about wanting to be considered to show interest by applying and to provide some solid answers to the questions even if they take a more casual tone or toss in some humor along the way. We do have our observations of members over time, but the answers will play an important part in the decision(s).
Hope that helps.
