Always looking to learn, and need not be electronics. Everything from cooking and welding to how to get the best shine on a woodworking project or mars exploration......
It occurred to me recently that there's a corollary to
nerd sniping that I think of as geek sniping. Basically, instead of being helplessly drawn into abstract or logical puzzles, it's the phenomenon of being immediately fascinated by the most intricate details of a much more specific, concrete, and often mundane subject. Probably both result from the same underlying psychological characteristics--particularly the inability to leave a newly discovered subject ungrokked--so naturally there's a lot of overlap between the groups who are susceptible to one or the other. Even so, the manifested behaviors are distinctive between the two phenomena, largely as a result of the differences in subject matter that would indicate different cognitive approaches. For instance, the quintessential resistor grid nerd-sniping problem indicates a strictly objective mathematical/analytical approach, whereas cooking, to use one of your examples, indicates an information-gathering and -synthesis approach that inescapably incorporates a high degree of subjective opinion.

Anyway, just something that occurred to me after I realized I'd just spent an hour researching mechanical pencils.
