Search Trends - Search Engine Marketing

Yahoo Answers is pretty cool. There are other answers websites out ther, but I think what makes this one work is the sheer volume of Yahoo users that are always online answering questions. Sometimes you'll get a lot of junk answers, but there are also a lot of legitimately good answers being given. I think the points system works as an incentive to answer well so your response will be picked as the best answer.

Yahoo just launched a Ask the Planet campaign to advertise their new offering. Every day they have a different prize--today's prize is a 3 oz bar of gold. To enter the contest you just have to answer a question in the selected category of the day. Today's category is business and finance. The more you enter, the more chances to win. It's really a genius idea for generating tons and tons of content in whatever categories they choose to highlight. The promo is linked from the homepage, but I first noticed it mentioned in the DMNews.
