Fighting the Machine

I belong to an online DVD rental store. I think they are a great idea if you live way out in the sticks and want to keep semi-in-touch with what the rest of the world is doing. Every week they send me DVDs, I watch them and send them back.

The website for this store has a fuzzy-logic system which looks at the movies you have rented (and the ratings you gave them) and then recommends other titles. This is a good thing because they have over 10,000 titles... and even I don't have enough time to peruse through all of those (you thought choosing a DVD from the local store was hard!).

The strange thing is their system is convinced that I am a geek and should be watching The Lord of the Rings, all of the Star Wars episodes and all movies with 'batman' in the title. We're talking the pastey skinned pizza eating PC using geek here... not your everyday generic geek (who can do useful things like fix washing machines, fill water tanks and change the brake pads on your car).
This is starting to bother me so much now I find myself ordering movies I don't necessarily want to watch just to try and convince the machine that I'm not a geek (if anyone wants to watch 'wicker park' or 'love the hard way' just let me know...)
And yet it still recommends LOTR, StarWars etc...

How does it know? How is this machine clever enough to see past my web of deception? And how many other geeks out there are doing the same thing to try and escape being labeled a geek by a machine?

Somehow I think this is a battle I'm fighting on my own...
