Career growth in Adobe Flex or HTML5 ?

Hi,

I have been working as a java/j2ee developer in an mnc from past 2 years.

I have worked on javascript,jsp,struts,html,css on the 1st project.

Now I am working on javascript/xsl/ Adobe Flex in current project.

I am getting calls for java/flex developer from jobsites.

Recently got a call for a Javascript/HTML5 developer. Is it a good option compared to Adobe Flex in current project?

Please guide me among these technologies which will take my career in right direction and good growth.

Thanks,
Rajesh

Flex is much more niche technology than straigt-forward HTML. If you want to open up future job possibilities, Flex isn't going to do all that much for you.
