Your Facebook page should direct folks here, not the latter. I mean, people do this all the time and it's obviously a personal choice. But if someone is on your AW site, which includes no other links anywhere else, why do you want to give them an out to go somewhere else? it's like having a brick and mortar store and when they ask a question, you send them to another store a few blocks over never knowing if they get there in the first place.
What's the first thing you do when you go to Facebook? If you're like me, you click on the red notification buttons and forget why you were there in the first place.
