What do you think a site that has many links that lead to dead-ends?
i can relate this question to driving on the road. If you ask for directions and the directions you keep getting only leads you to dead end roads then your going to think or feel that this person don't know what he talking about. You would then find another way of getting directions. Same as on the computer, if a site that has links but lead to dead ends you going to feel this site is not a capable site of getting valuable information and would try another site.
