Most of those things were largely too tiny to count as much more than practice runs for building actual space stations - in that list, the majority were less than 1/30th the size of the ISS - did you see the column on the side listing the cubic feet of space in them? 100m^3 is a ~4.5m box. So yes, we've put 11 space stations in orbit: only if you count a one-room flying can as a space station. I think we have a few more practice steps to go before we start hollowing out asteroids as GP was suggesting we do next.
