We spoke with Google rep Jim Prosser about +1. Here are some of our questions answered. What other questions do you have about the new product?

Says Prosser: "People consult their friends and other contacts on decisions. It's very easy and lightweight way to make search results more relevant."
Will the number of +1s affect search rankings?
Prosser says no, but adds that it's something Google is "very interested" in incorporating in some form at some point.
Who are th ese contacts we're seeing next to the +1s?
They are from Google Contacts, which come from various Google products, most notably Gmail, Buzz and Reader.
Will we see Facebook friends giving +1s at some point?
