There are a few reasons why you might not see posts on this friends page:

• Northern Track might have no friends defined. If you are Northern Track, you can edit your Blurty friends so they show up here.
• Northern Track might have friends defined, but all of their friend's posts might be over two weeks old (according to the times on our servers), and thus wouldn't be displayed here.
• Northern Track might have friends defined that post only protected entries that you can't view, because they haven't defined you as a friend in return.
