Title: Rails Scales!: Punctuation error in “Computer Science or Information Technology?” blurb (pages 3-4 of excerpt)

1. The asterisks used for Markdown on page 3 are appearing in the text rather than italicizing the text inside.
2. There are hyphens used were m-dashes belong near the top of page 4.
3. “Amount” is (mis)used for a count noun. One does not pour a gallon of computer scientists into a bowl. People are numbered, therefore “amount” is inappropriate and even grotesque in the images it evokes. In programming terms, people are integers, not floats.
