We're still trying to find the best approach to this, but in essence, our mission is making sense of this data. Some of this will have nothing to do with popularity - say, we might give you a concise overview of someone's code or professional thoughts. Other metrics will use social activity only as a rough validation. For example, if someone has 20 watchers on GitHub, they're definitely not a celebrity, but they have crossed a very meaningful threshold of "someone cares about this person's work".
Does that sound like a good direction to you?
