GWT - it seems to be getting popular, i dont know why.. Please tell me about the IT industry

Ok. this is not a uni assignment.
Just want to know the IT industry.
I have recently tried to apply a part time job in IT industry, look like GWT "Google Web toolkit" I have been self-learning Struts for a couple of years., it seems to be not popular any more, employers are now asking people with Spring and GWT skills.

I think IT career are not no longer promising.. Nursing would be better.
Also, Ruby on Rails seems to be getting popular, How can you IT experts catch up with all these new technologies, in oder to keep your employment.


Give me some idea about this industry..

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That's our motto.
Never stop learning.
In my olden days I read each new software's manuals from cover to cover.
Nowadays, I just dive into whatever technology I need.
How do you know what you need? Research.

On the other hand, don't go trying to learn everything. It will be just a waste of time.
Me, for instance, I've never touched Java, nor Windows technologies.
I never needed to.

Two steps:
1. Research
2. Focus

That's all you need.
