 I noticed a a few of my bloggers with categories called "1", so i had to
 look into it. What i noticed is a bug when the default category is
 changed, saving a post without choosing a category for it will cause a
 category named 1 to be created in the category list. To reproduce, rename
 the "Uncategorized" category to something else, which will cause the ID to
 change. Now go and write a post and don't select a category. Hit save or
 publish. Then go and take a look at the Categories list and you'll see it
 created a category called "1". Deleting the category will also delete the
 post.

 Taking a look at the code, i believe it has to do with the
 'default_category' value in every blog's options table. Inside
 wp_insert_post() function it says if there's no category selected, use the
 'default_category' value from the options table. The problem is this ID of
 1 doesn't exist anymore, because when you modify the "Uncategorized"
 category the ID changes.

 I'm guessing to fix this, either the 'default_value' option should be
 updated, or by making sure there exists a term_id of 1 at all times.
