As both of the new moderators indicated in their election Q&A, voting to close questions is the responsibility of the community, provided community members with sufficient reputation are actively engaged in reviewing close votes.
If the close queue is up to date (which it has been), I would ask moderators avoid solo closing unless a question is particularly egregious. When you do solo close, I'd suggest a comment indicating not just why you thought the question should be closed, but why you thought it was so bad that it couldn't wait for community input.
To be clear, I haven't seen any excellent questions closed. I've just seen new moderators be a little more closehammer happy than I would have expected based on the Questionnaire answers.
Please respond with an answer here if you feel your Questionnaire answers were misinterpreted.
EDIT: It might be time to have a broader discussion about the community expectations here. 3/4 mods seem to be saying pull back a bit while the queue is reasonably short, but this post has 2 up, 3 down votes right now. There is some appetite for a more aggressive moderation strategy among people voting on meta. I'd encourage those who feel this way to post an answer.
