"...someone else's right arm..." I fell down laughing so hard. Never heard that one before, but I'm not a native speaker.Of course not, assuming of course the theme being worked on is one with a dark background .
This current iteration with the large unbroken white spaces and washed out red looks quite a bit like the original google+. Far too little contrast overall, and I would really like a slightly sharper separation between posts. Personally I'd also give someone else's right arm for having a dark background with light text rather than the reverse, but I gather from the long-ignored 'dark theme is broken'-thread that we probably aren't getting one until everything else is done.
In short, I think this needs contrast, segmentation and less white. No white at all in fact, even a bright theme would be better off with a light gray tone.
