Is personal blogging dead?

As a blog marketer, part of my task is to look for bloggers who I can run my campaigns with. Criteria of qualified bloggers would include:

1. No less than 4 to 8 blog post a month for 3 consecutive months. (majority personal blog post)
2. Facebook fan page for blog
3. Blogger has social media presence in Twitter, Facebook, and Google+
4. Maintain a ratio of 2 to 3:1 personal blog post to commercial post (events, products, and paid post).

I must admit that when campaigns are done in a hurry, #4 gets compromised. But as client needs become more targeted with the kind of bloggers they want to work with, finding bloggers is not as easy it used to be.
