Technorati launched a new service today called WTF (Where’s The Fire, not the other popular acronym), designed to tell you what’s hot and why. Anyone can write a “blurb” about any topic, and then users vote for the best explanation. Though it’s an interesting concept, and is obviously trying to gain some initial awareness with its very “catchy” name, I don’t see how this is going to work out in the long run. Are people really going to want to explain why something is hot to other people? Do products like the iPhone even need an explanation? It seems like an idea that caters to the lowest common denominator, and one that requires explaining the unexplainable. WTF Technorati?
