I believe the only way to delete blog posts/comments is to have an admin or bureaucrat status. I think this is to prevent people from randomly deleting normal pages, which is good, but it's a bit weird that you can't delete your own comments or blog posts.

The best thing to do when you want something deleted is to ask an admin or bureaucrat, as they can delete it for you. I don't think there's another solution, except if wiki decides to implement the ability to remove comments, but I'm not sure if that will be happening soon.
