Maybe this is old news, but I really like Om's blog layout. Content is front and center with good typeface and size. Social buttons are easily found but desaturated so as to reduce distraction. Commenting isn't locked in to one auth system and encourages useful discussion. Does anyone know if this is a blog theme or is it custom made?
