as someone who is fairly invested in Google Reader, it pains me that this has been a UI step backwards.
It's lot less usable; defaulting every link to black, like the rest of the interface, makes scanning for links really painful, and there's still a good 130px of useless interface chrome that is taking up space for no good reason.
Blargh! Looks like I'm going to be loading some custom stylesheets very soon.
I haven't set up a style for google reader (yet) but Stylish extension for Firefox does a good job letting me customize sites. I don't use it on every site, but places I view regularly I tweak.
