The main argument I see for short variable names is that it's easier to read, and interpret (yes, ironically the exact same case the other side makes). In certain contexts (for small functions, math) code is a lot easier to read when using simple, or single variable names. Every now and then I see someone writing out math formulas with long names, and it's so difficult to grok the equation. Just use single variable names so we can grasp the whole thing in a single glance!
