i sometimes use multiple breadcrumbs.
my products can belong to multiple categories and thus there can be multiple breadcrumbs for a single page.
i do show all of the breadcrumbs on a page. i do try to calculate the path (if any) that the customer has used or is most likely to use and enphasise that one.
... what Andy Langton says makes a lot of sense though and i think i might think about that.
i don't believe that using multiple breadcrumbs has damaged me.
