Thanks for the theme - really great.
A couple of issues I picked up:
- '<span id="gotocomments">' results in HTML validator errors: 'ID "gotocomments" already defined' --- this can be resolved by changing the span to a class instead of the id.
- There should be some support for the goto-comments/add-comments to jump to the Disqus anchor - i.e. the following don't anchor when Disqus is installed: '<span id="addcomment"><a href="#dsq-comments-title" ...'
