You know, I've always attributed the increased frequency of semicolons in the writing of coders (my own included) to their commonness in programming languages, but I wonder if period-aversion among the tech savvy is a factor as well.
There's nothing wrong with using a period in that line instead of a semicolon, yet I would probably punctuate it the same way if I were writing it. Periods feel monotonous and final, and that can't be attributed to C-style languages alone.
