Here's a blog about the differences between a nerd, dork and geek:
"Nerd, Dork or Geek?
December 12, 2011 Emily Keller
Recently, my friends and I have been debating the differences between the terms ‘nerd’, ‘geek’, and ‘dork’. What make someone one but not the other? Well[, a]fter some debate and the creation of a Venn Diagram, I’ve come to some conclusions.
Nerd: This includes extensive knowledge of strange, specific thing[s] along with a lack of interest in anything considered ‘cool’, ‘hip’ or ‘trendy’. Nerds are intelligent and have extensive knowledge [about] their fringe interests.
Geek: Geeks are usually interested in technology/ga[d]gets, but there can also be specific types of geeks (Harry Potter Geeks, Apple Product Geek, Political Geek, etc.). They are also very intelligent and have extensive knowledge on their particular interests, like Nerds, but often this can border on obsession.
Dork: Dorks are identifiable by a lame or outdated sense of humor, coupled with an extreme lack of social skills. Dorks are often silly and enjoy fri[n]ge interests, similar to Nerds.
...I like to think I’m a little bit of all three."
