As others have indicated, someone will nofollow a link for various reasons: technical, anti-spam, or various site policies. That doesn't necessarily mean the link is counted as useless.
I think "nofollow" is a signal that is taken more or less seriously depending on the context AND site, and more often than not, the link will be ignored or its value discounted. There are times when it can help, though.
