Followup:
I see now that 'city' is in and 'region' is out.
Did you do that or did it figure it out on it's own.
Is there anyway to see the full decision tree without re-voting? I've accidentily refreshed a couple of times so my extra votes are skewing the tree but I'm interested in seeing how the tree evolves.

You can see the entire tree at http://cord-sa.appspot.com/dumpDT
How big is the pool of variables it can choose from?
Any insight on why it choose 'region' and 'browserHeight' first?
> How big is the pool of variables it can choose from?
Currently it is just: screenWidth/Height, browserWidth/Height, browser, browserVersion, os, referrer, city, region, country.
It picks the variables based on how well they partition the datasets into diverse sub-groups. This is the code that does that job:

Will it look for more decision nodes to add or are you stuck with region and browserHeight?
If not, how certain are you that you have the right data to accurately model the problem?
Yes, you guys are the guinea pigs, sorry about that :-) We'll need a lot more data before it is really going to get interesting.

There are quite a few more, I pasted them in another comment. You can also see them if you "view source" on that page.

I'm not, the fun of this is seeing how well people's favorite pets correlate with information their browsers give up automatically.
