I have been adding and deleting some blog posts. I have a categories block on the home page. I have noticed that the categories are not getting updated in the following instance. I have a category with one listing e.g. baby blogs(1). The user with the blog under this category deletes their blog posting. The category listing does not get amended and remains at baby blogs(1). I have to go into phpadmin and manually amend the entry. Well really I just delete it in this instance as the convention appears to be that if a category has zero listings e.g. baby blog(0), then it should not show up on the category listings.
