that looks really beautiful! we have a rather passive way of making compost too, and as you say, it's really the organic matter the soil needs. i like to use worm and compost teas so if we are just adding organic matter, those two things can take care of other nutrient needs. i think have a slow and lazy compost is great and i'm glad you're spreading that awareness that people can and should just start composting instead of not doing it!
I'm glad to find another fan of the "lazy" composting! After all, mother Nature has not turned a pile, ever! :D
And another thing, after we added our red worms to the compost pile, it started shrinking noticeably faster and the material in the end is mush finer grained. So even if it's an easy method, it's not that slow.
that's a fantastic idea- to add worms. and oh yes, the way mama nature does it. it makes so much sense to be more passive, i think ;)
