Gave most of my comments on msn but I may have found a slight bug, the random image on the top of the series page is sometimes the full size image, i just got a k-on 1280x720 image, but its not scaled so most of the image is not visable, and its just like the bottom corner is visable, going to eat bw/slow the page load.
I noticed my avatar appears beside an empty post on the top of the discussion part, see pic:
Not sure if thats intended or not, it kinda looks like a temptation to make a comment or post as the "add reply" button is there, so it looks kinda cool, but I think it would look more awesome if you used javascript to made a hidden div with the quick reply form, so they click it and the form drops out to write a post, without having to leave the page. I use that on my site for youtube and category edit forms, feel free to copy the script if useful. Or even just including the quick edit form already visable in the gap where a post would be.
A small suggestion for the user menu on the right, maybe add a link to the "sheduler editor" / koushin-editor.php
The Privacy and terms of use links are right on the buttom line, maybe adding a <br> to separate them from the browser's status bar.
Still think it looks awesome tho.
