Idea for a basic trend description website

So there are always these trends like "cloud computing", "Social Media", and "Mobile Internet" that us tech involved people hear about, get pumped about, and understand to some extent, but what about everybody else? I feel like there are lots of places that provide technologist/very early adopter news (focused blogs lets say), and lots of places that only cover things that have become big trends that the general public can understand (the New York Times for example), but what about a place that makes the biggest trends instantly comprehensible to the larger public that can make use of it? I'm talking more basic than Wired, and with a real focus on not only what the tech is, but what the heck its for and how it can help people. Specifically. Concretely. Like Twitter for example, its powerful, but so many people don't even understand what the heck it is for. Sure some of the nuance will be lost in this, but so what? We sacrifice a little richness for a lot of reach. Ok.
