This is a saturated field, as others said. But there's room for a competitor here. I would focus on the main social networks integration: Facebook, Twitter, and maybe maybe Pinterest. Everything else, including Mailchimp is overengineering.<p>Also I left a comment just now on your site. I wonder if it's possible to get all the Twitter oauth tokens when people enter through Twitter?
Nice product and website!
Haven't seen Dropbox used as a CDN before ;)<p>Being able too look at the backend of a demo competition would be great. This makes or brakes the tool for me. Additionally, I missed more information about the social network integration. Competitions and give-aways are big on Facebookm so how does it look and work there?
