Bob: I have removed the link on the Net Promoter article to your self-published web page. I wanted you to know there are two reasons for doing this:
- Wikipedia policy is clear in stating the individuals should not promote or refer to their own writings
- Policy is also clear that the articles referenced, especially if controversial, should be widely accessible and in independent publications. This reference is really neither.
Please see WP:NPOV for reference. WP:PG also provides a really good overview of the overall policies for page editing.
I can imagine this might be a little frustrating to you (this is the second time you tried to add this reference), but the policies are here to limit linkspam and self-promotion, which would otherwise run rampant and destroy the value of Wikipedia.
