Two things that others have stated prior (myself as well) that I still feel the same about.
I still would like to see something done to break up the excessive white space. Truthfully, staring at it for much time hurts my eyes. Makes it difficult to maintain screen focus, usually I have to look away for a seconds and close my eyes before looking back.
Some framing to better delineate posts could be helpful too.
Otherwise, while I still am not a "fan" of the look, it's more than adequately functional as far as I can tell. Was even able to finally fix the time stamp issue.
