While the latest Twitter update for Windows 8 doesn't feature a major overhaul, it adds a handful of useful functions to the app. Perhaps the most notable addition is multiple account sign-in that gives you power to easily juggle several Twitter personas. Another nice new feature is the ability to pin users' accounts and lists to your home screen, so you can follow them closely. Seeing as you can now also view lists on profiles, the list you pin doesn't even have to be yours. This makes it easy to discover new users you might want to follow... unless having Twitter feeds in plain sight makes you feel even more alone.
