While the latest social media obsession changes from week to week, the simple truth is that a well run blog should be at the foundation of most well-rounded social media strategies. Blogs don't get too much attention from the buzz-crazed social media industry anymore, but there is still tons of value in digital marketing through blogs, especially in B2B. Search engines love them, they are a great crisis-communications management tool, they can be great at aggregating your various social media activities across Facebook, YouTube and Twitter and are a simple way to build visitor engagement into your website.
