Facebook has its eyes on you Thursday, November 08, 2007
Om Malik has an interesting post regarding Facebook's new ad-mechanism, which involves over 40 partners at present.
It's one thing to know about what your customers do on your own site, but way different to be snooping on them wherever they go without their knowledge. That said, I wonder how many will care. For some it will never be acceptable; others may initially find it creepy; lots may give it a "whatever" shrug.
