I guess they could&#x27;ve simply tied the post range to the inverse of posting frequency - i.e. if you post once a month, you reach everyone, if you post daily, you&#x27;ll reach some random subset, etc.<p>But then again, Facebook has to get the money for their servers from <i>somewhere</i> (or at least enough of it to attract more investors). They could&#x27;ve chosen worse monetization strategies.
