Yuwie is a combination of several social networks but with yuwie you get a share of the revenue from the site for referring friends and having those friends duplicate what you did to recruit them there is nothing like this on the net and if it is, it isn't growing like Yuwie in the first 3 days over 100,000 people joined WoW i wish i could get that kind of traffic to my websites and it's totally "free". So if you join you can link Yuwie to StumbleUpon especially if you offer something for the public.
