Commentpress. I should check this out, it's a comment system that doesn't happen under posts, but in the margins of texts related to paragraphs. Actually a funny idea if you have longer texts. Okay, I almost only post single paragraphs, but I find the integration of comments quite nice - so the rendering of these small speech bubbles in which the comments then expand (at the moment, comments on my site are rather neglected, as they only appear on the detail pages, which are not even linked from the front for my short paragraph posts).
