'tis impossible to .... Rated 3 out of 5 stars

It is impossible to RATE this one without FIRST going to the creator's website and considering the author's goal: to promote material on 'raising venture capital' and the story about how he built and sold a system that offers subscribers data on web user demographics.
I suggest someone with the knack for it (see 2600 with analog set in trashcan on cover, either Winter 08/9 or Spring 09) to go through this code and hunt for obfuscated tracking code.
Feeling like Winston Smith
