Hi Alan...
Is there a case study -- where a silo is broken down and analyzed that I can use to understand this siloing concept !
My understanding of A Silo is -- you for example if you have a grocery store website - you create a dairy section then all related dairy products are found here and a deli dept then all cold cuts in this section etcc where all the pages are themed from the top then on downward, and trying to keep the silo 3 clicks from home
The breadcrumb -- not sure how this comes into play but if I keep the site 3 clicks from home at any time someone needs to get back to where they started from they are able to do it, so how does the breadcrumb help if I am already trying to keep the structure a 3 click structure for easy navigation and easy exit back to beginning.
