Does anyone have any thoughts on Disqus, particularly reviewing the usability and/or design aspects?

I see the service itself as meeting a need for those with static sites or who otherwise don't want to deal with managing their own commenting system. Disqus has also made some business decisions to increase revenue that have upset a few HN'ers¹. I haven't heard any complaints about usability or other design issues, though.

Even if you haven't heard them, we still get complaints about the usability of the product! It's what we did with the feedback that matters.

As for the business decisions, those were decided by VPs and the business development team.
