Yes, since only the expert needs to be signed in, you could technically take your own recommendations. It's more useful to browse together with someone else, though :)

i think you might have to be careful here... if i recall correctly, amazon's tos does not allow commissions to go directly to buyers.

you can't give shoppers incentives, definitely, but you can help them make the right choices with recommendations, technical help, etc. We will definitely be keeping people from exploiting it just for commission back from Amazon.
