If your not looking for an audience why bother putting what you wrote online at all? Writing has a purpose, one of those is sharing an idea. If there's no one to share it with why would you write it then?
For another example, look at Spotify. Granted, lots of horrible practices involved here, but the discovery aspect of the product is so good that many of us overlook those issues. I have found & purchased more music simply because of this discoverability. I win, the artists win, etc.
Everyone tends to lose when the discovery mechanisms suck.
