I get lots of my post ideas from cross-search-hits – people looking for subjects not really covered by my site, but with some words in common as far as Google’s indexing is concerned.
Well this site “Strip Mining for Whimsy” blogged it’s own cross-hit.
As I do, Joshua has spotted a hit with an item of interest despite the fact that most hits are literally about strip mining in his case. The common metaphor is the real link.
