Personally, I don't have anything against Disqus. They're a valuable (free!) service that provides a pretty frictionless method of adding comments to a blog (frictionless because they're everywhere – if you've commented on a blog before you likely already have an account).
That said, there are also articles like this, which highlight the huge amount of tracking that Disqus does, or lets other ad-networks do.
I don't plan on replacing Disqus any time soon, because I find having comments inline a valuable addition. However I also want to accomodate for the concerns by those who prefer not to have so many unrelated network requests when they visit a page.
Thus, I am introducing a "Comment with Disqus" button to allow those who want to read comments, or comment themselves to opt to load Disqus. But for those that would rather the network stay silent: that'll be the default.
