I have no idea,it's a new "feature" some kind of skript LJ offers to mix recent public posts and apparently the only way to see the gibberish produced is to post it, soo it may be curiosity, and apperently the skript produces an error but posts anyway, so people try it again and again. I have no idea whyt purpose it's supposed to serve, or why people don't at least delete the crap once they tried.
