I count near-future SF to be SF where I can see how you got there from here (ie, the society is ours-with-differences), and distant-future SF to be SF where I can't. I couldn't see the steps between us and Tally's society, so I call it "distant-future."

I happily admit that other people have different definitions. (And, indeed, I read very little far-future SF except for space opera, so.)
