Yahoo Answers has launched a new promotional campaign named Ask the Planet 2006. The Yahoo Answers blog describes how this feature will work;
Each weekday a new category will be featured, and each one will be accompanied by a question asked by a notable celebrity, expert, or even a featured user. For each best answer you receive in the category of the day you will get one entry for a chance to win the prize for the day.
The full press release can be found here and if you want to see the big brain in times square check out the pictures at Flickr.
