In trying to wrap our minds around Panda - or even the Google algorithm as a whole - I suddenly realized today that many people are still thinking of it like its a checklist, where a total score for each item gets ADDED UP. I'm sure it's not that.
All these people saying "oh no, now you're telling me I've got to do ________ (fill in the blank) are not understanding the complexity involved, in interrelated decisions that are made within the algorithm's calculation.
Remember that Biswanath Panda's specialty is decision trees. These are complex networks that are trying to simulate a human being's neural processes. Human processes do not work in a linear, additive manner, and neither does Google's algo.
