After clicking the Blog comments link, you will see a list of comments on all blog posts. You can use this interface to add comments, but the normal way is to comment on the blog post directly without logging in to the admin. The real purpose of this interface is to moderate comments.

If you have a lot of comments to sift through, it would be handy to use the filters in the sidebar. For example, if you want a list of new comments that have not yet been approved and aren't considered spam, select the following filters:

It's also worth noting that comments can be sorted by clicking the column headings to sort by Name, IP address, Date/time submitted, Is approved, Spam detected. Clicking a second time on a column heading toggles between ascending and descending order.
