I noticed a few queries regarding how to integrate Disqus with K2. There was another article out there, but they've rebuilt their site and have not kept the old article.

I have no idea how comprehensive the other article was, but as this is something I've done manually myself a few times, I've posted a quick tutorial.

You can see it in action here: thinksync.com.au/blog

And here's the tutorial: thinksync.com.au/blog/code/integrating-disqus-with-k2

Hope this helps!
