OFFTOPIC: Not Quite Natural Selection

Not an XML-Dev thing, so delete now if you like. 

After almost a week of posting to a blog, I find 
it is a lot of fun to watch the software selecting 
ads for my posts attempt to match ads to the 
content.  There is a rough analog of natural 
selection going on there and I wonder about 
the effects of that on the ecosystem itself. 

It's an interesting loose feedback system. 
I don't understand all of the I/O mechanisms, 
so I can't predict much, but it ought to 
have some sort of rough influence.

I wonder how it will evolve given that algorithms 
and not people are selecting these mates.
