Interesting... 5 minutes ago I had my first experience with Beacon while purchasing tickets for the new Batman movie on Fandango. I used to think Beacon was creepy, but now that I've actually seen it in action I think it's a fun little feature. Now all my friends think I'm awesome for going to the midnight showing. What is the big deal if Facebook knows I bought those tickets? The social points with the ladies are well worth the loss of privacy, imo.

I had this same experience and agree with all your points, minus the implication that "ladies" would naturally be impressed by my midnight viewing of Dark Knight.

You probably don't want all your friends to know about everything you buy. Especially if you have bad taste in music.

Isn't that why it asks you first?

that was my first experience as well. i didnt mind it.

I think the vendor he bought the products on shares as much or possibly more blame than facebook.

This should take care of the problem no?

This is really old news, and sadly, to my knowledge, it hasn't changed.
