Looks great, I think the website needs better code highlighting with larger fonts for text and code. Definitely disqus comments will help a lot. Are you looking for guest posts ?
I was thinking if it could be made into a wiki... but guest posts would be great for now. I just really like the site as it is the format that learn in, so I shared it here... I have requested the site owner to join this discussion... hopefully they'll like some suggestions here.
