I found this Digg/Stumble/Propel Better than Piqq http://www.iamoney.com/ They pay like 5-10 cents a digg/stumble/propel. You can boost up your traffic for your sites, as you can put your own links on there (digg link, stumble link, or propeller link (i never used propeller before)). It's being advertised on PTC now. So I guess it;s going to grow pretty big very soon. Their PTC ad says that it will be on invitation soon after the launch. Right now it's still open for everyone. So you should join now before it's locked on invite.
