I got a request today for a HTML5 website. I’m always afraid when a client asks for a specific technology. I’ve gone through this very scenario with Flash about 10 years ago! When I asked for project requirements, I didn’t see the need for HTML5. Mind you, I’m excited about HTML5 and use some very useful tags already.
There is a lesson here, don’t ask for a technology, ask for a solution to your problem or your requirement. The best solution may incorporate the technology you want, often asking for a specific technology limits your solution.
Some of the best solutions are derived from a combination of several technologies. Don’t limit yourself just because it is the latest technology available and you want to stay ahead of the curve. Leverage the latest technologies to improve the solution.
