We rails people tend to think of Rails as the center-piece of web development. The same thing can be said of .net, Spring/Java Server Faces, Drupal, Python or name-your-web-framework-of-choice-here people.

Web frameworks are just a component of web applications, and if you want to succeed you better know the miriads of other components beyond your rockstar code.

In my session I will talk about things you must take into account and tools/techniques you should master if you want to make a difference in web development, independently of your development language/framework.

Talk delivered at conferencia rails 2010 in Madrid, Spain.
