Not a chance!
With a quick riff on Elizabeth Barrett Browning's "How Do I Love Thee? Let Me Count the Ways ..."
Z'berg could screw me to depth, breadth and height
My wallet be screwed, feeling rather light
Privacy sadly lost in Facebook haste.
He’d screw me, Zuckerberg, every day
He’d screw me freely, e’en in dark of night;
He’d screw me purely, in many new way.
Screw me with a passion he’d freely choose
Give my money, unprotected, on faith?
My magic card’s sixteen digits to lose
With my lost info — I hate thee to death,
Broke, hounded, hassled — as my pain accrues,
I shall but loathe thee with my daily breath.
I mean, seriously, besides the possibility of Marky Mark losing my information (which I don't store for autofill ANYWHERE), I'm sure this is just a step to spamming me with Facebook Store come-ons.
Also, per the end of the blog piece, why would PayPal partner with Facebook on this? A few years from now, I can see a massive attack of regret.
