Q:

Review queues always empty

I am not able to review any post although I have enough reputation (more than 1400) on my Stack Overflow account.
However, the review queues always show zero contents.
Up until now I've only reviewed one item. Is something broken?

A:

At your current reputation, you can only see the "Late Answers" and "First Posts" (I believe). These queues are often empty and, even when they're not, a large group of users constantly patrols the queues and will snatch up the opportunity to review.
Once your reputation increases, you'll gain access to some queues that typically have a handful of items in them at any one point. Once you reach 3k, you can drown in all the close reviews you can handle...

(Minimal reputation artfully added in red)
