All of us might have seen breadcrumbs on most wordpress blog.
So why not implement a breadcrumb for the blogger blogs.. For those who don't know what a breadcrumb is,here is a little defenition from wikipedia.

Breadcrumbs or breadcrumb trail is a navigation aid used in user interfaces. It gives users a way to keep track of their location within programs or documents. The term comes from the trail of breadcrumbs left by Hansel and Gretel in the popular fairytale.

The trails like Home >> Label >> Post Name are the breadcrumbs.
