That seems to be how I understand the difference between the two words. I have heard the phrase "the Nerds will inherit the earth," before -meaning that they'll eventually be the ones in charge. Geeks, not so much. Nerds make things and geeks appreciate what they've made. Aside: If a link has been posted before and its the exact link, then you will be notified prior to posting that it's been posted in the past. BTW, this doesn't mean that you cannot post it again. That's totally fine. What's nice about the notification is that it links you to the past post, therefore you can see if there is a conversation there etc.
Yeah, although I think in some circles the distinction is more about the scope of individuals' interests, like just a "nerd" is someone who appreciates or excels in academia, whereas a geek has more specific interests (e.g. computer geek, sports geek, etc). (Side note: I have heard "the geeks will inherit the Earth", but that probably has more to do with geek & meek rhyming than anything else.)
