If you're a page admin on Facebook, have you ever "liked" one of your own posts thinking that the "like" would show up as from you, yourself, and not the page? I know I've liked plenty of WebProNews posts, thinking it would say "Josh Wolford liked this," but instead seeing "WebProNews likes this."
Now, Facebook has made it incredibly easy to switch between your true identity and your page admin identity when you want to comment or like a post.
Now, when you go to a page of which you're on admin, you'll see a new tab on the top right called "Voice":
Clicking that will drop down a little bar that reads "You are posting, commenting, and liking as _______ - Change to ________," where those blanks refer to your page name and your personal account name:
Clicking on the "change to" part quickly lets you post as your true self, so you can like your page's posts to your little heart's desire. The functionality doesn't exist elsewhere, as the "voice" tab goes away when you go back to your News Feed.
Google+ has allowed users to easily shift between personal and page admin accounts for a while now, and it's great to finally see Facebook give page admins an easy way to do this.
