Most people who join a network marketing company are gone within a few months, often worse off than when they started, and Kevin Lau puts that near the front rather than at the end. What follows is his attempt to explain why, and his answer is that people buy tools when what they lack is a system.
He is unusually willing to name things. Ann Sieg's list of lies about the industry gets examined rather than dismissed. Magnetic sponsoring gets broken into steps. Backlink builders and article submission robots get reviewed as software with limits, not as magic.
On choosing a company he gives you criteria and tells you to check the rankings yourself, which is the opposite of how most people in his position write.
The lead generation material forms the largest run, covering autoresponders, tribes, article marketing and free sources, and it repeats itself in places.
If you are deciding whether to join something, read the company evaluation posts before you read anything the company sent you.
