“Why JSF” or maybe “Why Not”?

In his blog, Keith poses a question “Are you using JSF or intending to?”. So here goes, these are my reasons for learning JSF.

1. The answer Keith didn’t want. It’s a standard. I know this is a very boring and possibly not very good reason, but I’m interested in the new Java EE 5 spec and JSF is a part of the new spec.
2. I don’t know JSF yet. This may sound pretty obvious, but I want to learn JSF because I don’t know it. If I don’t know JSF well enough to develop applications in it, I can’t really say whether it is fit for the types of applications I develop or whether I should be using some other framework like Struts or Wicket or Spring MVC.
3. I want to learn Seam. Seam is based upon JSF, so its probably a good idea to get a good grounding in the basics before progressing to the next stage.
4. JSF will supposedly allow me to develop web apps quickly. Whether this is true or not, I’m sure I’ll soon find out!

So, will I ever deploy an application with JSF? I don’t know, I’m still in the early stages of learning. I know there is plenty of information on the internet regarding peoples opinions of various technologies including JSF, but how much of it is FUD and how much is reasoned criticism?
