I have noticed my organization creating new team sites (full, default sites) whenever they need a place for documents. For instance, a team site library will have hundreds of team sites: Team A 2012, Team B Software version 1.2, Team B Software version 1.3.
This is clearly bad organization, but I need some facts to back up my intuition. What kind of overhead is associated with constantly creating new team sites?(file size, database entries, etc.)
Maybe I'm wrong and this is just a matter of preference.
