There are a few reasons why you might not see posts on this friends page:
utenok_mu might have no friends defined. If you are utenok_mu, you can edit your LiveJournal friends so they show up here.
utenok_mu 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.
utenok_mu 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.
