Though some people may be content to group all geeks into one category, it is actually more complicated. Some people think they can spot a geek a mile away, but can they actually do? Even more difficult is to determine exactly what makes somebody a geek.
Geeks come in all shapes, sizes and fandoms. Some are fluent in computer coding languages while others are fluent in Klingon. You may find some geeks hanging out at the Apple store and being more helpful than actual Apple employees while others are regulars at the local library. The San Diego Comic-Con fills up with cosplay geeks each summer. On the other hand, some geeks just have a very expansive set of knowledge, including pop culture, sports, music and films. Others have exclusive knowledge about the most obscure topics imaginable. These geeks can give you very specific math equations or identify each type of butterfly they see.
