Blogging as a way to establish relationship and for referrals

Blogging is a powerful way of making friends and sell products. Think of it this way. Those who are faithful followers of your blog would have established an online relationship with you. As they follow you thru day after day, they will get to know you better. A trust is therefore established. As they know you, they tend to trust you more and more and would be more convinced to buy a product that you recommend. This is similar to MLM except that it is not multi level and also the relationship established is not limited by the time we are awake. And the other advantage is that there are almost 1 billions people (as at today) who can potentially become your friends. A friendship beyond physical and political boundaries.
