the barn door - trendy or here to stay?

I love the barn door. Everywhere you turn, there is another barn door that someone is incorporating into their home. They are very practical for places that would otherwise not have space for the swing of a door. And they have an industrial feel that is all the rage right now. So is it a 'right now' thing, or is it like the stainless steel appliances that everyone thought was a fad but has now been tested to be a classic? What do you think?

Regardless of your opinion on where they go in ten years from now, right now they all look awesome to me!
