If you didn't already know, Facebook is targeting the celebrity set with a new iPhone-only app called Mentions. However, when it launched in July, it was only available to musicians, actors, athletes and government officials in the US. Today, the company has lifted one restriction, making it available to socially important people in over 40 countries worldwide, including the UK. The bad news is that you're probably not a big enough deal to use it. Mentions is designed to help VIP's interact with fans via their verified Facebook page, allowing them to post updates, host live Q&A sessions and identify if they're trending. Tyrese Gibson supposedly used it to share news of Apple's Beats acquisition with the world, but really it's the overworked PAs trying to keep on top of their employers' social lives who will be secretly rubbing their hands following today's expansion.
