Breadcrumbs are Not Just for Birds

I personally see tremendous value in breadcrumb navigation. Foremost, breadcrumbs should be easily seen. Breadcrumbs typically should be placed toward the left-hand side of the page and below the global navigation, why? Because that is where most web sites present them. Successful User Interaction (UI) is taking advantage of existing design conventions (which are user-friendly) that users are familiar with. Breadcrumbs are not the functionality to get creative with. Just think about it, when have you most frequently used breadcrumbs?
