I asked a handful of top bloggers for their top Do or Don’t for writing a business blog. Here is what Microsoft’s Robert Scoble, Seth Godin, Halley Suitt and others told me. No, these folks are not CEOs or CXX execs but they know how to write a blog and they have many thousands of avid readers who follow their every post. Seth (author of Permission Marketing, Purple Cow, etc.) has evolved into a big name brand, partially because of the exposure he’s gotten through his blog.
