Quotation guideline

I'm noticing that prog posters differ in the use of an extra newline after quoting a previous poster. I propose a standardized method of quoting, which we should attempt to come to some sort of agreement on, arguing for and against.

Method:
Con Newline

    | quoted text
   
    -comment

Sans Newline

    | quoted text
    -comment
