Got to add that I reckon the scope for discussion around the stones is pretty broad. I enjoy the dry, archaeological stuff, I really do, but there's plenty more to talk about, surely.

Lots of peoples beliefs (spiritual, political, etc) are bound up with these sites - I can't see a problem with covering that.

As for endless repetition/subversion - why not just ignore it. People will modify their behaviour if they want to be included.
