Ascendancy

Web design isn't IT, it's more of an artistic / graphics field. If you were a web programmer and programmed web applications in PHP, ASP.NET, Perl... then that would be a bit closer to IT, but still not quite an IT field. A real IT field is someone like a network admin, server admin, IT Technician, etc...

As for the security of the job, that would really depend on how much you're willing to work. With more and more teenagers spending 50 hrs a week studying and learning computers, there's at least 3-5 14 year olds from every high school in America who call themselves "web designers". So if you want to stand out in the field, you just need a damn good portfolio and to be able to outperform the youngins
