Well, I have read some review blogs in order to see what persuasion techniques they use. I don't know if it's just a technique or these authors are really knowledgeable about the subject but I have ready many reviews with intro paragraph like this: "I worked in xxxxx for years and I know this product is very good" "I were shopping for best TV and I bought xxxxxxxxx and so far it's seems as a great choice" "I spent many years writing for magazine on this topic and I'm sure you shouldn't miss xxxxxxxxxxx" "My friend works for xxxxxxxxxx (some cool company or magazine) and he recommend me xxxxxxxxxx" or something like this: "You should buy xxxxxxxxx product. I have worked for xxxxxxx for years and I know a lot about that stuff. Since I was child I had interest.... " etc etc I don't know if: - author is lying in order to gain trust? - author isn't lying What do you think?
