Types of Nonprofit Blogs

I've been thinking about the different types of nonprofit blogs.

Nonprofit blogs can be divided up into two major categories -

1. Blogs for a nonprofit organization
   
2. Blogs about nonprofits

Blogs about nonprofits can be divided up even more. Types of blogs about nonprofits include technology, fundraising, communications, and volunteering. These types can overlap.

Are there any other types of nonprofit blogs?
