Long story short, posts marked as "backdated" STUPIDLY don't show up on friends pages. And since I had my screed futuredated so as to always be up top (like geeksdoitbetter has on her page) , LJ STUPIDLY would never accept any of my entries unless they were backdated. So they were all backdated, and never showed up anywhere. Fan-fucking-tastic.
This is now fixed, FSVO fixed.
