Would you also consider creating a static "how to" site that generates revenue from ads to not be passive income? I think that's the most basic example of what HN considers passive.
We're just defining words here anyway. I think a core component of what people think of when they think "passive income" is making a disproportional amount of income relative to effort put in. Until those proportions get dis'ed, you're just working at a sub-optimal job.
