A pretty good attempt at nailing the obvious differences between geeks and nerds. Nerds also tend to be a lot more productive, making genuinely new stuff, while geeks tend toward a more passive fanboy-ish consumption and a little tinkering at the edges (mild gadget hacking, graphic design tweaks). Geeks, for instance, would never consider creating a 3D train simulator of the 20th century industrial railways of Stoke-on-Trent. But to a nerd, it’s a completely natural thing to want to do. In a shed, ideally. It’s still something “normal” people can relate to (heritage, games) and so doesn’t shade into that hazy realm where nerdy becomes weirdly eccentric.
