Selected, non-involved editors?

If they were interested or competent with respect to the subject they would be involved.

This is hardly the case. Many contributors who are both interested and competent with respect to particular subjects nevertheless do not edit pages on those subjects, for a variety of reasons.

1) Based on liability or ethical concerns, professionals in various fields (doctors, lawyers, etc.) might choose not to edit articles related to their specialty, so as not to create any relationship with the reader or potential for malpractice complaints. 2) Contributors who also make a living from their writing might avoid covering the same subjects on Wikipedia that they cover professionally. This is true whether they receive income from their writing directly (why give something away when you can get paid for it?) or are paid by an employer (in which case the employer might argue that what they write on the subject is work for hire, and object to having it contributed to Wikipedia or licensed under the GFDL). 3) People with a distaste for the intense disputes that rage over some of our more controversial pages may consciously avoid those subjects, regardless of how interested or competent they may be.
