Build Value. That's the answer. A certification is only a step forward, and just one small part of the puzzle. The problem with wanting to be a 'web designer' is that everyone and their dog who can open FrontPage or Dreamweaver figures they are one.Every high-school kid has a portfolio of web pages now.
