I must be a dolt, I have never seen this, and I've been around lurking around here for a while. Where does one see this on the node's page? All I see is "Comment on blahblahblah", "Download Code," etc. Or is it only there before it is approved? Oops, no, I just checked an unapproved one. Does it have anything with my name not appearing in the list under "Other Users" (yes, I'm logged in because I see my theme and name at the top). Sorry, but I don't want to miss out on any of the fun around here.
Update: Now, my name *is* on the list. Weird.
