Blog post listing page doesn't look great

This page looks pretty bad:

http://rspec.info/blog/

I think it's largely because of #47.  Honestly I think I would prefer a sequential listing (with no pagination or snippets) like http://myronmars.to/n/dev-blog over what we have now.  However, I think @mootpointer and @JonRowe have discussed improving things here?
