Tag's, folksonomies, and Google Suggest

IFTF's Future Now makes a point about one problem with "folksonomies", bottom-up taxonomies that people create on there own :

None of the current implementations have synonym control (e.g. "selfportrait" and "me" are distinct Flickr tags, as are "mac" and "macintosh" on Del.icio.us).

I wonder if a Google Suggest like system might help narrow the list of "lazy" tagging for Furl, Flickr and Del.icio.us? By "lazy" I mean the habit to use the shortest possible name for something.
