It works quite well for the dog blog next to my name, but I found it far too distracting and annoying when I put it on one of my forums so I took it off again.
I will remain with adsense. WidgetBucks is just trying to cash in on the hype, but it will be impossible for them to maintain their high rates for unproductive traffic. How is it possible to pay $0.50 per click for low quality traffic thats not converting? Advertisers would go bankrupt and If it was possible google would continue doing so, but widgetbucks may be a good alternative for those that were banned.
