"Experts" say that regularly using someones name while talking to them makes you come across as more sincere. When used on me, I find it makes the speaker sound disingenuous. It's as if they were only doing it as cheap way to appear sincere.

When someone is in the same room as me, I don't tend to think of them in terms of their name. When someone is introduced to me, it doesn't tend to register. They are the person just there with those characteristics. At one place I worked, I had the piss taken out of me for tending to ask who someone that was introduced to me was the moment they left the room. Subsequent places tend to have wheeled people in to be introduced (mostly due to the shit hitting the fan, coincidentally, just after employing me).
