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

• bits and bobbins might have no friends defined. If you are bits and bobbins, you can edit your LiveJournal friends so they show up here.
• bits and bobbins 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.
• bits and bobbins 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.
