From their post on Hack Week 2012, Disqus has been working on bringing apps to all major mobile operating systems. That of course includes Android, iOS, and Windows Phone. It has been confirmed and rumored on other websites before the official announcement on the Disqus blog, but I wanted to wait until Disqus makes their official "press release".
Indeed, Disqus has taken its first step in their new goal by releasing a new Disqus Windows Phone app. The app, dubbed Disqus, allows you to explore and engage in discussions, view notifications, manage your profile, and more. The app is available on the Windows Phone Store right now.
Disqus apps for other mobile operating systems will come later on, as they gather feedback and improve the Windows Phone app. If you have a Windows Phone, let me know of your feedback in the comments below.
