POSSE is a great principle, but I'm talking about a different phenomenon: being voted onto the front page of HN, /., or featured on a huge subreddit, a tweet by some influencer with 100k subscribers, etc. The 15 minutes of fame, which hopefully leave a bit of a lasting audience, connections to sister sites mentioned in the resulting threads, etc.

The biggest problem of any indie publishing is obscurity; not that nobody cares, but rather nobody has an idea, and has no way to have an idea.
