"A quality, coming from a person rather than from an office, that inspires intense loyalty and devotion; often has religious significance, linking prophet and followers". http://www.alanmacfarlane.com/TEXTS/dictionary.pdf
(Online, different types of charisma get people followers on sites just as Twitter, or fans on Facebook. Brands can have enough charisma to outwigh the charisma of many people. The Old Spice guy did just that after a transmedia capaign allowed him to respond to fans through YouTube and Twitter, connecting the charisma of the brand to an audience of adoring followers. Justin Beiber's Charisma net him hundreds of millions of fans, and Lady Gaga is near-diety in her power and production capability. She is a charisma producer, not a follower).
