Twibbon.com is an easy way to promote awareness of causes on twitter. You can create a twibbon “a cause symbol” in 3 easy steps and soon the supporters will be proudly wearing their twibbons on their twitter profile images.
Very nice simple idea to market a cause on twitter. I tested one cause I believe everyone should promote, “IE6 Must Die for the Web to Move On”! yes! Currently there are about 4700 twitter users who promote this cause.
