LinkedIn is a pretty insignificant part of the article. I mentioned using it as a proxy to gauge the size of your professional network, and to find local interest groups. Overall, LinkedIn hasn't really helped my business all that much, other than increasing my web presence for credibility searches.

I'm rather surprised that you felt that there wasn't much content. I spent around seven hours writing and editing the post and it draws on several years of in-the-trenches experience.
