Blogging and Employment

[Update: I think I wasn't clear enough. One of the areas I'm asking for advice on is how or whether to broach the subject of the blog with a prospective employer. I'm thinking in terms of employers possibly being concerned that I blog.]

I need some advice...

I'm considering pursuing a job opening in a non-profit working on behalf of military families. I believe I'm highly qualified for this type of work, but much of the proof of my skills and qualifications resides in this blog.

Any thoughts on how to handle this?
