I wonder why?

What seems so special about this picture that it has had over 6,500 views on Flickr?

I admit that I like it but don't think it's all that better than a lot of my shots of the moors.

Composition is OK but nothing outstanding, yet for some reason or other just after I posted it on Flickr it 'Took off' with view after view. Made me think it was something gone wrong with the website.
