I have recently closed some questions. The common thing was that I was the only one doing that.
Many users have the privilege, they can vote to close... yet no-one does. So my message is: If you see a bad question, you should vote to close.
When you see a good post, you vote up, when it's wrong or not useful or not clear, you vote down. When something just doesn't belong, then vote to close. That's what we are supposed to do as a community. Mods are an extra help, they are not supposed to be the only ones who take the decisions. Now the community is small, but then it'll grow and it will be impossible for just some mods to handle everything.
This is why high-rep users have such privileges, so they can help. You are almost-mods, so prove that high reputation by actively participating.
