Sure, its even easy. Go grab jekyll http://github.com/mojombo/jekyll/tree/master, which can turn your haml/sass, textile or even markdown into static html pages with links. Host it yourself or on github, and use one of the comment hosting services, or throw a link to any technical-ish post here on HN, and people can comment on it.

I have a static blog and used to have Disqus for comments. I've since disabled Disqus, no fault of theirs, I just decided that I didn't want comments.

So can you put Disqus up on HTML pages?

Yep, Disqus can be added to a website by putting a Div that Disqus will fill from a piece of javascript.

yep, it's what I do (Jekyll + Disqus) and it's actually very easy.

example and instructions from someone else's blog:

Sounded like an interesting proposition. Would it be possible to do this and use Disqus?

You should be able to pull in comments from an outside service using a <script> tag. And if that service doesn't exist, hey, startup idea!
