As for the "decisions" thing, I assume they are talking about decisions re: admin actions, like blocking and page protection. Personally, I'm not as interested in opinions from non-admins about administrative actions. There are two reasons for this: First off, people who are not admins don't have the kind of experience with these problems -- from the perspective of someone trying to solve it -- to be able to talk about it with some kind of awareness. Second, I assume (perhaps naively) that if someone were able to understand admin-related situations, think them through, and come to a decision, they would be admins themselves already.
