2010 Twitter Head Contest The 2010 Yam Jam Twitter Head Contest is available to anyone with a Twitter account. You must be at least 13 years of age and be an avid Operation Turkey supporter. Limit two tickets per winner. Operation Turkey and the Austin Yam Jam staff will search Twitter for the most tweets sent by Twitter account holders using the tag #yamjam. A "tweet" is a single post sent to on follower, so 1 post that gets to 1,000 followers is equal to 1,000 tweets! The top producer of Twitter coverage will receive two spots on the 2010 Austin Yam Jam Guest List at Threadgills on October 17, 2010. The winner will be contacted on October 15, 2010. Please use tag #yamjam when posting on Twitter so we can track your progress. Tickets cannot be exchanged for cash or sold to anyone. Void where prohibited. Enjoy the show and thank you for your support.
