Not sure what you mean by implication, but the goal of letting users
'tag' their profiles (and other things like groups and collections) is
that we want to be able *find* these objects by their tags. In
previous Django tagging applications I've used, you could easily
generate tag-clouds, see 'related' tags for a given tag (i.e. things
that were tagged with xyz often were also tagged with abc), and for a
particular tag find out what other objects were tagged with it.
The tags will be used in the 'new' search implementation (see related GNIPs)
