he's right but should consider to erase the word "nerd" from his voc.
He's absolutely right on this topic. I hope some people in his position read this article. But the author should very quickly drop the word "nerd" from his vocab. Personally I don't really like being considered a nerd. (For me "nerds" are people wearing strong (very strong) glasses, think constantly in a way no other understands and tend to be pretty shy). And another important advice: Don't give your "herd" (I hate this word if speaking of humans) the idea they are kids. This could destroy all efforts you speak off. Although they most likely won't tell you they hate you for this.
