I guess it's all part of the "silver bullet" and "hype" culture. People want something that will automatically scale their new giga-scale web product that is going to be "the new facebook!", and managers want something that will make them rich without too much work, so they sign up for all the latest cool tools instead of thinking deeply about their real requirements and good old fashioned hard work. Some of the latest cool tools really _are_ amazing and worth every penny and more, but I'm sceptical about some of them...
