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