The free Twitter app begs the "Why do I need this?" question when compared to the desktop social media client or the Twitter website. I found myself drawn in, though, by the clean, elegant design. Social media marketers and Twitter junkies will want to at least check to see how their handles appear, as the design differs from the Twitter Web client. The app probably isn't something you'd want to rely on for managing multiple accounts, but it's a good free Windows 8 app for individuals. The natural brevity of Twitter is a strong fit for the Live Tile concept, too.
