Takes All Types is a non-profit, grassroots organization that aims to create the first nationwide network for blood donation, and they have taken the innovative step of bringing their cause to Facebook. When a user adds the new Takes All Types (TAT) Facebook Application, they enter their location and their blood type, if they know it. If there is an emergency need for that blood type in a certain geographic area, TAT will notify any potential donors in its system. Users can also sign up to receive updates by phone, text message, email, RSS, or fax. On Facebook, you can display a TAT Card on your profile to show your support, become “a fan” of TAT, or share information about the organization with your friends. Even those unable or unwilling to donate blood can become members and support the cause by simply spreading the word to their online friends. Takes All Types promises to expand in the near future to other social media outlets besides Facebook, and aims to use online communication and networking to eradicate the problem of blood supply shortages across the U.S.
