People with far more time than I have have already discussed the topic of nerd vs geek, but here is my two-cent definition:
Nerd: A person with highly detailed knowledge of any subject
Geek: A person with highly detailed knowledge of any subject and can do something useful with it.
A nerd is someone who knows all about computers; A geek can help you fix you computer.
A nerd is someone who can recite all the lines from every episode of Monty Python’s Flying Circus; A geek can succesfully employ a reference to the “Dead Parrot Sketch” in a PowerPoint presentation.

While perusing through the pages, I came across the Bag of Holding messenger bag, and much like a scent of pine and smoke can bring back a decades-old memory of summer campfires long since gone, the phrase “Bag of Holding” brought back fond recollections of my days of yore playing Dungeons & Dragons.

I can do nothing useful with this information:
Therefore and ergo, I am a nerd.
