Disqus should be added to the .com site. That's all there is to it. There's no amount of convincing you can do to me that tells me otherwise (and no, I don't think security is a good excuse). I believe Disqus functions a lot better than what WordPress offers, no offense to WordPress workers themselves or whatnot. I would just feel a ton better with Disqus. Installing WordPress is far too complicated for my tastes (and very time-consuming), so I would like it if there was an option to import or use Disqus via the .com site.
The blog I need help with is chiphigheelsvidyagames.wordpress.com.
