I have been using Disqus for my comments on my comic blog at lolmace.com (which I really need to start updating again). Disqus has a lot of cool features including video commenting using Seesmic. I have been debating wether or not to switch my blog comments to Disqus. Today I switched them to Disqus. What changed my mind was the ability to export comments, so if I want to quit using Disqus, I can export my comments out of their system. Soon I will be able to import all my past comments into the Disqus system. Now if only people commented on my blog.
