What is a scope of content management systems and related technologies?

Hi,

Has anyone worked for Content Management Systems (CMS) development in any of these tools like Interwoven Teamsite&Livesite, AEM CQ5, Sharepoint etc.

I just need to know the scope of these technologies since there are not much vacancies for any of these so how to apply for such kind of jobs.

Because as a Java Developer and web developer there can be ample amount of opportunities and vacancies but as a CMS developer there are rarely any vacancies.

So, is there a way to stay with CMS with many CMS vacancies and job opportunities?

Any suggestions?

Thanks in Advance.
