Comment(by donncha):

 An example:

 The category "test" on blog 1 will have the same cat_ID as the same
 category on blog 2. Rename that category to "test2" on one blog, and the
 other blog will still have a category called test with the old cat_ID.

 test2's cat_ID will be different though.

 cat_IDs are global across all blogs, makes doing things like sitewide tags
 much easier!

 You can always do `is_category( 'test' )`
