Google Mac blog hacked?

I was browsing my RSS feeds today and came across a very strange post on the Official Google Mac Blog.  Screenshot below.

Strange RSS Entry

I went straight to the blog to investigate and, lo and behold, the offending post has now gone. Is this another example of Blogger being hacked in a very public way? Or is it an inside job?

We’ve seen Google Blogs being hacked before, so you would have thought they would have sured up their security. In fact, I seem to recall that when a previous hack occurred, the offender just tried to register the account through blogger, no trickery involved.  This new message posted earlier today certainly implies a similar situation. What do you think?  Is it just a Google staff member not realising that the blog they just registered for is publicly viewable?  Or something more nefarious?
