Unless I'm reading this wrong, one takeaway is that the pool of people with RoR experience is so low that anyone with some time to spare can sweet talk their way into a developer position<p>...or that interviewers are schmucks and will hire just about anybody who took the time to read through a book and hack out a demo app.
tl;dr version.<p>Learn rails. Write some demo apps. Read other people's code on GitHub.<p>Appears like a useful article but half way through it turns into an advertisement for why you should hire the author as a consultant at $150 an hour to help you land a job.
