Comments Boxes?

I've had the webpage for Commentbox.io open for so long now. I've not pulled the trigger on it yet, but I'm really thinking about adding comment boxes to this site.

Not sure if I'd do it for all pages, or just a few, or even just one 'guestbook' type page yet...

Decisions decisions, and all of them wrong.

EDIT: In case it's not super obvious, I ended up using HTML Comment Box instead, Commentbox.io refused to work for me! so HCB it is, I will probably add it to most pages for now.
