I don't guess you need to rely on a plugin for getting cross domain JSON. You can use jquery's 'jsonp' dataType.
Looks like in your first example, you are requesting text/xml, but in the second one, your type is just "text" which might be causing the url to send back a differently formatted response. For JSON data, you could also try a type of "application/json".
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
