I may be misunderstanding your claim, but otherwise I think the article would actually interest you. Here's a quote from the paper:

"Instead of starting with the hard problem of why an arrangement of particles can feel conscious, we will start with the hard fact that some arrangement of particles (such as your brain) do feel conscious while others (such as your pillow) do not, and ask what properties of the particle arrangement make the difference."

Is that not investigating what makes something conscious (i.e. an observer)?

EDIT: after a bit of reading, this is not intended for non-scientists. The introduction is interesting, but otherwise your time might be better spent reading critiques of this paper instead if you're a newbee like I am. Here's one such critique: http://blog.jessriedel.com/2014/05/13/comments-on-tegmarks-c...
