Corporate Blogging

I have been reading quite a bit of literature about blogging. From multiple sources, too ... Most of it focussed on corporate blogging. And, something surprises me ...

There is plenty of stuff out there on the use of corporate blogs in the marketing domain ... How organizations can use blogs as marketing, or as PR tools ... To reach out to customers, create customer communities, and to react to positive and negative press.

A question that I have been trying to think about ... Does this mean organizations cant use blogs at the corporate level for anything other than specific, market facing, or customer reach activities? Is there not value that organizations can unlock from social computing in areas other than marketing? Of course, there is. Which brings me to the question ... Why is most of the thought revolving around marketing and PR activities? More on this soon ...
