Of all the AppSumo deals I've purchased, this is the only one I rely on every day. Other deals have been great too but SocialAnimal is critical to my success. For example, I get to see content that has the potential to go viral and decide if I should write something about it too. It also allows me to be up-to-date with what's going on with my competitors by seeing what they're writing about and the industry as a whole by tracking keywords.
