True, but even without anything to prevent Javascript running Disqus has the nasty habit of causing the page view to jump around as it loads due to there being no non-dymanic HTML fallback version loaded in place first. Depending on the connection, it can take some time after the rest of the page has loaded for comments to appear (and if set to dynamically load on scrolling down, this is even more annoying), and on poor connections you can end up having to refresh an entire page to convince the comment section to load correctly. This later issue is mostly a problem on mobile devices.
