C++ may not be the worst programming language ever created,
but without a doubt it’s the worst ever to be taken seriously.
(Mason Wheeler)

I added the functionality of Disqus-comments to my blog software. Because why not.

However, the comments are not shown normally, to protect your privacy. They are only shown on single-entry-pages, and only when you actively pass &disqus=yes (or follow a link that does so), that is, as long as you do not click on the corresponding links, there should be no difference (well, except for the links, of course).
