I'm interested in the "automatic feedback" response thingy.
Is it only positive or does negative feedback get immediately generated?
What will be done to prevent someone from creating multiple user accounts to +1 himself? Will feedback from local (i.e. same Hometown forum) members be not counted due to regionally proximal IP addresses?
Almost all of my EE transactions are Face-to-Face local deals. It'd suck for their +1's to be ignored because they live close to me and the system thinks they're a shill account.
(although, only about 20% of my EE deals even result in a +1, the rest never get reported, so I guess it can't be much worse)
