More like Old School -- Asimov, Campbell, Heinlein, Bradbury, Ellison (new Old School), Farmer.
Yes, definitely that as well. But I recall how newbie it was to use anything but the term "SF" to distinguish the genre from fantasy, sword & sorcery and horror.
I like those you mention and revere other great ones such as Theodore Sturgeon, C.M. Kornbluth, Clifford D. Simak, L. Sprague de Camp, Murray Leinster and many others. Those people really stretched my mind.
