Yeah that kind of irritated me a bit because authorized them to access my Facebook and then I was told that I would be e-mailed once they are ready for me.
I didn't even get a welcome letter or anything in my e-mail. I at least would of felt better if I had some type of acknowledgment that I signed up for the service, and a status screen where I could check on the indexing process.
It was almost like: "Thanks for letting us use your Facebook data to build out/test our service. We will be in touch."
I wouldn't of signed up if I knew the sign up process was going to be like that.
