Library webmaster's software-which programs to learn?

[Joan Graham]

This is my first post - hope it's on topic. Would like the list's
opinion as to what programs and skills are essential to library
webmasters. HTML and javascript, yes, but what about Flash, Fireworks,
java, perl,  C++, stylesheets and XML....are they now being used on
library websites? Will they be, in the near future?

Second question: is there any survey or other data on job descriptions
or salaries for library webmasters?
Thank you all for your comments.
