I love the idea!
It could also be nice if one could customize it to only show selected posts. That way a coding snack author could use it as a mini website to show off just their coding snacks and other software they have created as a result of being a DC member, and not include any other posts, if they don't want them.
Maybe even allow users to publish to it from their private area and actually use it as a blog, if they want.
As far as the look and style, I think it would be cool if it had the look and feel of the DC blog
Might be easier too. You could allow users to promote their own posts to their own blog page in the same manner that posts are currently promoted to the dc blog.
