How much traffic is needed to earn money from AdSense? Possible income? – Meetup

These are two questions I get asked a LOT.

1.  How much traffic is needed to earn money from AdSense?

2.  And what are the possibilites for income?

I’ll answer that question here (sorry, if you came looking for it now) but only after the Meetup that is happening in Palo Alto, CA. For those who don’t know Palo Alto is home to Stanford and Facebook and neighbors Mountain View which is home to Google.
