Welcome to the forums! You have not been forgotten.
As I understand it, there is a race amongst languages to make web pages for mobile phones.
There are over 30 languages for wireless products now, but I believe the "two favorites" are WAP Wireless Application Protocol and HDML.
Honestly, I don't know which way to go. Major cell phone manufacturers go either way. I have said it before, it is a gamble with your career: learn one and win big, learn the wrong one and hurt big.
While cell phones have gotten smaller, there is now a reason to make them bigger: screen size.
I have often wondered what is going to happen. Will people give up their pc's permanently? I can't believe they will entirely. Will people use their cell phones to browse the web? In certain situations, yes.
Will they buy something off their cell phone? I can't believe they would do so under most circumstances, but I am sure they would want to have it with them when traveling to look up the address of a restaurant or hotel in a strange town.
Yes, webmasters will be affected. I think it will take a little more time, at least in the United States, to understand just how they will be affected.
One thing to always remember, "Trust above all else the knowledge of your craft." As a technical person, you can never learn too much. The trick is to keep adapting to the changes. Technical people will *always* be going back to school.
Is XML the way forward. You will not hurt by knowing it.
