MSN question

What does the yellow star besides some people's names mean on the MSN contact list? (MSN 7)

i.e:

It means they have new content on their contact card. Only just worked this out by clicking it and having a roam.

What do you mean by "new content"?

- Changed nickname?
- Changed personal message?
- Added pictures?
- New blog thing?

What defines whether the star appears or not?
