When it comes to SEO, a lot of what works and what doesn't is bounded in the technical limitations of what it's possible for search engines (eg, Google) to calculate.
A huge amount of internet marketing is nothing to do with this (eg, it's marketing), but fundamentally SEO itself is based on 'beating the Google algorithm', and therefore understanding what it's possible or impossible for the algorithm to do gives you a clear upper hand over those without that understanding.
tl;dr: I'm wondering what technical background BHW users have. I have frequently seen people here claiming that it's impossible for Google to do things which are clearly possible, or possible to do things which are clearly impossible.
So...what's your technical background?
EDIT: To give a little more background, my thinking here is how you would give an answer to a question like "How can Google detect duplicate content?" to determine at what point Google will not be able to see duplicated content is really duplicated from the perspective of an algorithm.
