What I never understand about the "more exposure will dilute our membership quality" is that it's a social voting site. If you're going to share something with a community that has open registration, and gets exposure by sharing links to other networks (such as Digg and Reddit), this sort of thing is inevitable. I'm glad it's received the exposure it has because it's become such a great content generator. I don't really see the harm in this growth.
