When to support HTML 5
At all times I try to support browsers that have javascript enabled. I ensure that important functions are available to all and not a single user is alienated because of a lack of javascript. There may be some special features that non javascript users are missing out on, but overall the site is still very usable for them.
A lot of companies do not support this idea as they believe it will cost more to build the site that is usable in both forms. Generally what happens is certain major functions are enabled only for users with javascript. If this is the case then you should push for change and try to make your company see different, but that is another story.
HTML 5 is the future of web development and works in all major browsers. Internet explorer does need a few javascript hacks to get it working, but it does work. Therefore if your company only supports clients that have javascript enabled, then your company supports HTML 5.
This very site uses HTML 5 and after turning off javascript, the site is still usable and looks ok. So when is the time to start using HTML 5?. Right now.
