+1. I can speak to having to educate a large community on some of the  
merits of these concepts. Moving to the other names would create a lot  
of confusion such as "why don't we just run an Oracle RAC if we just  
need to scale the Database, record sets, and fields"

With Columns, SuperColumns, and key spaces - they know they are  
working with something different and do need to think a little  
different. I realize this creates some educational overhead but it  
comes at savings in sense ambiguity that would be introduced by the  
proposed shift.
