I don't think it's a problem. It's posted in the right place -- as soon as I saw this node I checked Perl News, and there it was.

I don't know about anyone else's voting habits, but I tend not to vote on news or announcements, if that's what you meant by 'self-aggrandizement'. Making "There's a new version" be a reply to the 1.0 node means only the sharp-eyed folks watching the Newest Nodes page would catch the announcement.
