Involve the blogs with the product during its feature-spec stage. Not only will you get better press from them once you need it (people like to write about their influence...), but you should also get some good feedback from the blog authors and users. I'd contact blog owners during dev, tell them, "hey i've found this pain, and I'm building MyProduct to solve X, Y, Z. Do you think these are the biggest problems, as you see it?" This way you can get press, you can network, you can get good feedback from potential customers... And the blog owner gets to feel special, and look special, to their readers. Win win.
