On the heels of announcing it amassed 500 million users, Instagram is adding a new feature to help its global audience better understand each other. The filter-driven photo and video app will get a translation tool "in the coming month." When it arrives, you'll be able to tap a "See Translation" link to make sure you know exactly what a bio, caption or comment says. Instagram currently supports 24 languages, but it did explain that older comments and captions may not be privy to the update.
