The words "nerd" and "geek" are often used interchangeably, as if they mean the same thing. They actually don't:
geek - An enthusiast of a particular topic or field. Geeks are “collection” oriented, gathering facts and mementos related to their subject of interest. They are obsessed with the newest, coolest, trendiest things that their subject has to offer.
