Ask HN: Tips for success posting non-simple ideas?

I've noticed that on the internet ( HN, news sites, Reddit ) what often works the best, gets the most upvotes and comments is something that presents "the simplest version of the idea."

Necessarily this version is incorrect and misses the nuances of the original.

I guess what I'm asking is -- how can you get beyond conveying something so simple as to be almost useless, but still have it "take in the subject's mind" ( i.e, become popular, viewed, read ) ?

This is relevant to marketing which is very relevant to what a lot of people on HN are trying to do with their startups and side projects. So please have a think and contribute your ideas!
