We had not announced it here yet because we're in the middle of a gradual rollout of the commenting feature to make sure that everything works as expected. If you don't see it for your site yet, you'll be seeing it soon!
This is not a fix. It is a commercial app you could have added a long time ago. This requires a commenter to create a Disqus account, something most casual commenters will not do. I assume they also have to give Disqus certain information to create an account they by and large won’t want or use that much. Additionally this app has started to fall out of favor because of negative impacts on speed, etc. I will be removing my blog from GoDaddy as soon as I find a suitable replacement host. This experience has made me appreciate WordPress in spite of its flaws. I think I will just go back to it.
By default, Disqus requires commenters to log in to help prevent spam. However, if you go into the Disqus moderation panel you can change that by going to Settings > Community and checking the box to allow guest commenting.
Except for advanced features like the one described above, you shouldn't need to go into the Disqus moderation panel for anything. We've taken the time to do a deeper integration with Disqus that allows you to handle everything within your website builder or from your own blog posts where you can moderate inline. We've also negotiated a contract with Disqus to allow everyone using the feature to have ad-free comments, normally an experience only available at paid levels.
Disqus does commenting well, so in this case, it made the most sense to work with the experts to meet the needs of our GoCentral site owners.
