I've had people ask me for sequels, but I've only really written one. Two, if you stretch the definition. Shiny Daniel Trap was written for a prompt, and when the same person (plus a couple of other readers) later asked for a follow-up, I wrote Shiny Daniel Sequel.
Phantom Intelligence is more of a companion piece, but one might also think of it as a sequel to Statistical Ghosts.
Overall, though, I find it almost impossible to force my brain into the shape needed to extend or add to a particular story... even though I'm often asked.
