Whether you once lost three hours to cat videos, or you just really love watching the videos of your grandkid serenading the camera, you probably have at least a passing familiarity with YouTube. So long as you limit your interactions with the site to watching videos, you’re unlikely to expose any personal information while on the site. However, if you post videos and like or comment on them, you’ll want to check your privacy settings.
