You are in the ballpark but you are making some generalizations too.

Heavily fished rivers that get beat to death on here and in the media are non-issues to me. When I fish these, I go in fully expecting a crowd but will fish them anyways when I know the fish are in. Whether or not they are talked about is a moot point. Sometimes people will be there and, in your example, sometimes they won't.

Where you went off course a little bit is the issue of smaller, lesser known (and fished) streams. It is the mentioning of these rivers that chappes peoples a**es. I've got a handful of these that I learned about through personal dedication, curiosity and lot's of hiking. The only reason they are good is because few people know about them. Now I'm not into giving mis-information (let's just call it lying people!) but I do understand why certain people do in the case of small, intimate streams.

Sadly, I have one stream that has been ruined by the effects of the internet. A few years ago someone couldn't resist doing a brag-fest about how well they did and how much room there was for everyone and how no one was up there etc....Within the day! I had more guys up there fishing in one weekend than I had seen in the previous 5 years combined. It has never been the same. Of course everyone has the right to fish where they want and I don't proclaim to own the river. But I also know that my hard work to get some great fishing was ruined instantaneously by our friend the internet.
