Categorization + Whether a POI must have location

Hi,

 

Once we use some real world categorization schema as defined in say
Wikipedia, it lets us define categories for almost all the 'entities' we
know.

Columbia Pictures films
<http://en.wikipedia.org/wiki/Category:Columbia_Pictures_films>   It HAS
NO LOCATION

 

My concern was whether we are going to let users create POIs for Art of
Computer Programming, Easter ,The Social Network and millions of such
'real world' entities( for which we can identify some category in
Wikipedia but the entity itself has no location).

 

That is are we going to let users create POIs belonging to categories
which do not support location in their semantics.?

Can users create these POI's with location as unknown.?
