As far as favorite places go, once the internet was invented, forget it. There's always gonna be someone who will blab about it, and then the fire-making, trash leaving, shampoo-hair-in-the-lake crowd will follow. The last time I was almost back from my favorite place, I met a group heading in for it. Someone devoted a whole chapter of his guidebook to it (my favorite place).
I'm pretty sure this crush of visitation happened well before the internet. Increased use coincided with more people getting interested in the outdoors, and more people having disposable time and money, and more guidebooks.
Many times I've seen favorite, relatively unknown places experience a boom in visitation, after a guidebook was written. In the Adirondacks, Peaked Mountain had no real trail till a guidebook disclosed the area in the late 70s; in New Mexico, Tent Rocks was little-visited till the "Hikes near Santa Fe" guide appeared in the 80s.
It's the way of the world.
