I just discovered how to put up an opt in form which 'Auto-fills' with viewers facebook name and email address.
Now, I guess the idea behind it is to :
A: save time and make it easier for people to sign up,
B: collect the BEST email address.... (people are more likely to read emails sent to their facebook address??)
What I'm not sure about is how they actually perform?
I'm wondering if it would scare people AWAY seeing a form automatically populated with their details !!??
Anyone have any experience with this??
