Ask HN: Marketers, should I keep or sell my blog posts?

My cofounder and I are putting together some great "how-to" blog articles to help promote our project http://wpstatus.com

The question is, do we try to get published on outside major blogs or should we just publish to our product blog and try to build our own audience?

My feeling is, if we tap into these larger blogs with huge audiences, that might result in more exposure.

Any advice would be great. Thanks in advance!
