Vondoom: I am born and raised in the New York/New Jersey area, and that so called naming convention is wrong, walk into a library or Book Store and you will find all books that are Science Fiction, scifi, or hard Science Fiction all listed as SciFi or Science Fiction, they are not deliniated, I find Heinlein next to StarWars next to Clark, ect. (even though they are alphabetical you know what I mean) and IIRC clarke did not write the story i am refering to until the 1950's when either sputnik was up or there were definitive plans to make satilities.
BTW while I do tend to deliniate between Hard Science Fiction and not I more a less refer to it as Classic Science fiction and others, becuase mostly the Genre of Hard or Classic Science Fiction has gone into hiding recently (I realize there are some but not as many as there were a little while ago now that most of the great masters are dead: Heinlein, Asimov, Hubert, Dickson, ect)
