Here via network. I'm bi and I write stories about people; but as a reader, I don't always want to read an informed perspective in my slash fic. A lot depends on the characters and fandoms involved, and sometimes a PWP is exactly the brain candy I want to write/read. Also, I'm a very action-oriented writer: if it doesn't impact the plot in some fashion, I probably won't put it into the story. I understand the desire to want a bit more history and realism in fic, but I am not sure the inclusion of such is always appropriate.
