It's the time to use the new technologies like HTML 5. Everyone of us knew about what this is and how easy now to generate some nice and rich UI without put much efforts. No complex javascript, no silverlight or flash is required most of the time and many more advantages. There are plenty of changes in CSS too. So, I believe we should start using HTML 5 in our applications. Because almost all browsers are supporting it.
After I have written some posts on Visual Studio intellisense on Jquery and SharePoint 2010 ECMAscript Client OM, I want to write similar on the intellisense for HTML 5.
This is very simple process than any other we have followed.
