Pebbles trail

I admit it took me over 7 years to notice this, but strictly speaking, the metaphor of the breadcrumb trail is totally absurd. The breadcrumb navigation is supposed to lead the user back along the way she or he came. But – remember the fairy tale – the trail of breadcrumbs did NOT help Hänsel and Gretel to find their way home because the birds had eaten all the crumbs. Their first version of scattering pebbles, however, fulfilled the task very adequately.
