Businesses and organizations advance and succeed partially on their ability to grow and effectively disseminate knowledge of their specific industry and/or service.

Human civilization had advanced because of culture, writing and standing on the backs of giants. Do that with your organization with a blog about things specific to your industry and help build your search engine ranking in the bargain.
