About a year ago I read an article at CNET News written by Dave Rosenberg, the title is Need a job? Learn Drupal. At that time I was in need of work I can count on, and when I read the article, I am increasingly convinced that Drupal is where I should go.
It was my belief at the time was right, after a year has passed and now I've got a great new job, even my economic condition is much improved after learning Drupal.
Thanks Dave, you're right!
