It's mystifying, but in fact some of them are worth reading and commenting on (though some of them seem banal).
I have a blogspot blog too, and there I continually got hits on a post I headed 'Smurf porn' (It was nothing to do with Smurfs, in fact, nor porn). So I included the words in two more titles, and the hits just won't stop! I even posted a satirical story (which stops before it gets to the adult stuff) in order that the hitters would actually bother to read past the first line of the post... All of these hits came from Google, so that tells you something.
Mind you, I don't think a wordpress post headed 'Smurf porn' would get you on Freshly Pressed.
