What's the significance of the "primary blog" and why would an admin want to change one primary blog to another?
Thanks in advance.

Looks like it's the blog that wpmu defaults to when a user logs in, if the user doesn't specify the blog in the subdomain (or directory-path - if that's where your blog name is specified).
Any others?
That's pretty much the reason.
And if they leave a comment while logged in, their name will be linked to their primary blog.
