All the technologies

Do people really think that throwing every new piece of cool technology at a project will make it a success? I love new technology and used to spend time playing with new Frameworks etc so I could find a use pattern for them. But very few of them made them into projects because their was no value to be added from doing so.

I have seen so many projects where the business case for building them is based on keeping a technology stack up to date. Great if that is going to add value or provide a competitive advantage. But spending time and money to move your website to the latest and greatest JS framework is not a valid reason.
