I like the idea of "Human Wave" science fiction. A lot. It was introduced by Sarah Hoyt in this blog post: http://accordingtohoyt.com/2012/03/21/what-is-human-wave-science-fiction-3/
The Human Wave idea is related to the idea of Punk Writing, presented in the Punk Testament of The Boomer Bible, the book Seren was reading toward the end of TSP. (There's a free online version at http://theboomerbible.com.) They may not be exactly the same idea, but both share the fundamental premise that literature doesn't have to (and generally shouldn't) fit the mold of the type of 20th/21st-century literature that all the toniest critics prefer. Which is to say, Human Wave and Punk Writing can both feature stuff like plot... action... good guys and bad guys.
Without revealing too many spoilers, The Smelly Planet probably doesn't qualify as either Human Wave or Punk Writing. Both movements allow for books to be satirical, but I suspect TSP is too cynical to qualify for either. The next book I have in mind (not a TSP sequel) should be a better fit.
I thought I'd have more to say on the subject, but I guess I don't. I expect to touch on some related subjects here in days to come, though, so check back later!
