Yesterday I posted about how internal blogs can save your organisation a great deal of money.
With this in mind, consider this post which was written at least a year ago by Corporate Blogging which highlights what the firm, IBM has been doing.
Alex Barnett had a useful post about the issue at around this time as well.
As he writes "What makes the internal blogs really useful is RSS - it isn't like subscribing to an internal distribution email alias - the thoughts, links and comments become an archive of knowledge and conversations, captured in the blogs - filtered and distributed by the magic of RSS in a spam-free method. All potentially discoverable through search applications. Internal blogs can also an effective venting and ranting platform, pointing out the good and the bad of the internal workings of a business and the competition in a safe, behind-the-firewall, environment.......Given their potential I'm quite sure internal blogs will soon become a default feature of the internal communication / KM landscape for businesses large and small."
