Video ringtone-sharing

Yet another social-networking niche! But a very logical one, given kids' love of media-sharing with cellphones (70% of 13-to-17-year-olds in Europe and the US share content on their phones, M:Metrics found). Now think about the online-safety implications. The promo for Vringo.com, aimed at people in their teens and 20s, "shows a teenage girl holding up her phone with a video of herself: 'Hey Frank, what’s up, what’s going on? Come on, answer your phone. You know you want to',” the Kansas City Star reports. Nothing about safety or privacy in the company's FAQ. It just says, "You can share any Vringo you shot yourself with the whole community. You can choose the option from your handset, to upload a Vringo you shot and make it available to every one."
