Someone asked me about the history of the method naming in activerecord and I wasn''t sure where to point them. For example, there was early criticism noted of has_and_belongs_to_many in this old post from 2005: http://hans.fugal.net/blog/2005/10/03/habtm/ I was mentioning that many_to_many is not used because there are a few different ways of doing that via has_many :through and
