Here’s a thought for you: what about an internal blog within your organisation?
In the marketing course I finished this summer, one of my colleagues said her boss wrote daily in his personal blog purely to communicate with his staff. In it he discussed what had happened recently, his reactions to it, his ideas for the future, things he wanted done that day/week/month, any news his employees should know, celebrated successes and analysed mistakes, and published advice and top tips that was relevant.
He used his blog as not only a method of communication, but also as an archive. Employees could refer back to past posts (using the category or archive systems) to check on decisions, requests or commands made. Instructions were written down that could not be lost, and could be referred to later.
The blog was made private to selected readers or contributors, so the search engines could not access it. It was a perfect medium for communication and the staff could also use it to comment and leave feedback. OK, it may seem to be a little impersonal, but don’t forget the blog could be accessed by any computer in the world, as long as the correct usernames and passwords were used, so ideal for employees on the move.
WordPress have so many features that can be adapted to suit your business in a myriad of ways. What else would you use your blog for?
