Get rid of the "post saving" feature, which takes up screen real estate but is probably used by a minority (though some people here say they use it, so I may be underestimating). Or hide the "Saved" link in the top bar unless you have actual saved posts.

(You could also make saving an option that can be activated / deactivated in the options, but I don't think the "Save" link under posts is as much a waste of "screen real estate" as the link beneath the header, which is distractingly close to other useful links)
