Well this is a first. Windows Phone is getting an official app before Android and iOS. The app is Disqus, the very popular blog commenting platform (which we use here).
Many, many websites across the internet use Disqus. It allows users to sign in with a variety of social accounts and build up stats. The app allows users to participate in conversations on websites that utilize Disqus (like our own).
Some of the key features include notifications for replies, the ability to follow people and get updates from them, star and vote on comments, and live tiles to show recent information. The app is optimized for Windows Phone 8 and previous versions, plus it has wide live tile and lockscreen notifications.
Disqus is free for all versions of Windows Phone. You can find it below. If you frequently comment on websites you will want this app.
