Flashy and pretty, but as a UI I find it places too much visual emphasis on form over function / style over substance. The biggest example I can give us that I don't think the bright neon blue left border on posts should be so much more eye-catching than the post titles. If I were to change things, I would probably try to find a dimmer shade of blue for them, and/or add some additional decoration to post titles so that they more clearly are the first thing my eyes are drawn to when scanning the page.
