Stirling and the NOSS Gateway
I must say, I hadn't expected you to like Stirling's works, Zendexor, because of the entire premise's reliance on COMOLD! That said, I'm glad you did like them- they are some of my favorite NOSS works.
I've put some thought into the NOSS and its differences with the vanilla OSS. Typically, NOSS fiction features the old worlds while updating the technology to match the current standards of Science Fiction. This is evident in stories such as Allen M. Steele's "Martian Blood" and "Frogheads" and also in Stirling's "Lords of Creation" series.
Now, I've enjoyed both mainstream science fiction and OSS fiction for a long time, and so I might not understand the minds of all the Stids out there. However, it seems to me the objection to OSS fiction is usually something like "It's unrealistic." or "Its out of date."
It strikes me that NOSS books, and Stirling's "Lords of Creation" in particular, might serve as a sort of gateway drug for mainstream sci-fi readers. Its focus on realism could pull them in, and, hopefully, the OSS dream might make them stay. It's a thought, anyways.
