I don't know if this is targeted or not but I just got an email indicating that the Marriott Rewards Visa Premier Credit Card from Chase Bank is offering 20,000 bonus points for every for every friend you refer who gets approved for the card! This is much better than previous referral bonuses I have seen where they offered 5,000 or 10,000 bonus points per friend up to a cap of 50K. This 20,000 referral bonus seems unlimited. If you didn't get an email, log in to your respective MR or Chase accounts and hunt around for a link.
(Also, if any of you are currently not MR Visa Card holders and would like the 80,000 bonus points for opening an account, I am happy to Private Message you a referral link )
