It never hurts, when making the case for business blogging to the powers that be, to have a bagful of examples of companies whose blogs have paid off. There are several in an article appearing in a piece on the MSNBC site, including a Minnesota company that custom construction work. Northfield Constuction Company’s Ray Cox started his blog two years ago “to better connect with current and potential clients.” Cox says the blog has enhanced the company’s reputation for being personal and understanding.

Also mentioned are three Fortune 500 companies using intranet-based blogs to communicate with and get feedback from employees. The businesses aren’t named, but the Internet marketing and technology company that built them is, along with several other PR, marketing, and communications reps.
