is it your blog?
did you set your settings to "moderate all comments"?
coz when i did, and made a comment on my blog, it still says 9 comments and there's a queued thing beside it and the comment i added is coloured maroon.
if that's so, only you can see those comments and you need to approve them before other people can see them.
there's a checkbox on the right side of the comment. tick it and something will show up on the lower right corner of the browser. select approve then click go.
