Learning about instance variables and don't understand why the instance variable "name" in the code example below is not visible where as "title" is. Could someone explain this to me and why I hadto use the "self.get_name()" method (which I don't understand since I pulled it off the net) to get the value out of name?
Thanks

Classes are objects in ruby and can have instance variables, so when
you set @name = "Steve" where you have put it you're create an
instance variable on the class rather than an instance variable on a
particular instance of the class.

So what is the distinction between a class instance variable and a class variable (ie @@name="Steve")?

mostly the odd scoping stuff which means that @@foo in an instance method and @@foo in a class context refer to the same object.
