@escoville: I don't think #2 was a red herring at all since "impressing" is used intransitively here and not transitively, they way it would normally be used: to impress someone
@HappyWarrior: I'm not sure what you are trying to say. They are headlines, which I have pointed out, and as such meant to be truncated. I don't think there's any need to "appropriately complete" them. German headlines are frequently no different, and I think cookie crumbler is smart enough to realize that.
Edit: having said that, I almost forgot to mention that M-W does indeed list an intransitive entry for "impress" as well:http://www.merriam-webster.com/dictionary/impress
: to produce an impression
But I also think that's a fairly rare usage.
