I don't think Beacon's job is to suggest products to other people, just to notify them that you have made a purchase. I wouldn't consider someone buying something as an endorsement for the product, but I do think it's an interesting, though useless, thing to know.
It gives that manufacturer and product publicity though. And that publicity is linked to your interpersonal relationship with your friend. Although that isn't explicit endorsement, I would argue it's implicit endorsement, and nevertheless that affects your propensity to buy a product and your view of that manufacturer.
I have no problem with iGot's explicit endorsement, but Beacon's implicit endorsement appears to leverage your interpersonal relationships for marketing benefits, and I'm not keen on that idea.
That's the distinction I was going for, with iGot you have choice to endorse a product or not. Maybe it would be good to combine the two. If you allow Beacon to post your purchases you could then use iGot to tell your friends what you actually think about that product.
I don't think Facebook makes Beacon data available to App developers but it would be interesting to play with.
