[thelist] Ajax - Which one to learn on?

[Chris Ditty]

I know a lot of you are currently doing ajax applications and hopfully, I
can gleen some insite from you all.

As someone that has an interest in Ajax for both commercial and personal
usage, which one is the one to learn on?  I intially found BackBase and was
rather impressed with thier tutorial.  I also found the one from Yahoo,
Adobe Flex and a few others.

In you guys opinions, which is the best one to use?  I'm currently leaning
towards Flex for the tutorials and future chance of business uses.
