Hi Marnix,

Thankyou for your reply and your observations.  I hadn't thought of blogs in the way you present the example.  I think you are right, which may explain why blogs are increasing in popularity. 

I do agree management tend to think in one school.   I also think consultants in the main position themselves in one school. Both parties by camping in one school limit any initiative from the outset.

Again thank you for your insightful comments.

Regards, Graham
