Discussion among Nerds

While I'm not old, I wouldn't consider myself a young Nerd. I'm 20, approaching 21, and I realise that the Nerds of today probably have different ideas of why they are Nerds. Likewise, Nerds from older generations will differ in views. As such, I have started this topic as an open discussion for anyone who considers themsleves a Nerd. I want to to why, to see if there is anything consistant between the generations that makes a Nerd.

I am aware that some people may be offended to be called a "Nerd". To these people, I say: "Either you don't belong here, or you are in denial." Being a Nerd is not a bad thing. From what I have gathered by talking to other Nerds, a Nerd is an unpopular person, who enjoys intelectual pursuits, and usually is good with numbers/money. They differ from other outcasts in that they are generally mathematically minded. Similar outcasts are the Geek (Sciences), or the Computer Whiz. These 3 groups are usually able to get along, for they can relate in several areas.

That is a basic description of a Nerd in my generation. I'll give a more detailed description later, as well as what I've found of Geeks, Goths, Emos, Computer Whiz's, Artsy types, and unspecified outcasts. But for now I open up the topic to Nerds, to give their 2c about current, and previous, generations of Nerds.
