According to Klaus Schneider's new paper, Americans love to state their names:
Schneider compared the openings of small-talk conversations between teens at parties in Ireland, the US, and England. One of his findings was that about 85% US teens identify themselves early in the conversation, but only about 12% of English teens do. The majority of English teens (56.7%) start with a greeting only (e.g. Hi), while Americans prefer greeting + identifying themselves (60%) and sometimes explicitly asking for the other person's name.
