Facebook’s Secret Rate Card Exposed!

Valleywag has the story.

Here’s the part I was interested in.

The main question, though, is how much its sponsorship business can grow without offending users. Only one sponsored story can show up at a time on a user’s homepage, which limits inventory. And with Facebook apps now vying for users’ attention, will sponsored groups still spread as quickly from user to user?

We need a word for this. You know, the time between when a startup is ad free and then that critical point when they “turn on the ads”.

What to call it? Any suggestions? It needs a buzz word.
