Great post over at the Church Of the Customer on Citizen Marketers. Some great pointers to Citizen Marketers:

• George Masters and his homemade iPod ad
• The volunteers who market the Firefox web browser (24 million download in 3 months)
• People who create fan sites like this one for the Broadway show “Brooklyn the Musical”
• The quirky guys behind the campaign to bring back Surge cola
• The creators of TiVocommunity.com
• Customers who post photos with their reviews on Amazon.com
• The people who created ads for the “Bush in 30 Seconds” contest from Moveon.org

Also love the mind maps from their Customer Evangelism University.
