I've seen this (no message)/(no author) type of post before in other forums and also in an email list. I always thought it was clever, even thought provoking... though the repetition does detract from that a bit. Who knows, it might even be the same "no author" who posted all of them!
What I found curious about this example was that (no author) decided to post it twice.... Assuming, of course, it was the same (no author) who did it the second time around. This being cyberspace, you never know for sure! :-)
