RebelMouse now offers a paid option to power your web domain for a monthly fee. RebelMouse, a social publishing service, has received plenty of buzz for helping users create a dedicated page for all of the content they share on social networks. Now, the company is launching a paid feature called Powered Sites that lets users create and manage a more social webpage from their own custom domain or sub-domain. For $9.99 a month, RebelMouse will automatically populate your website with your posts from social networks like Twitter and Facebook, and it will provide you with a full publishing platform to post videos, blog entries and slideshows. The goal is to make it easier for anyone with a webpage to keep it active and fresh even if you're not actually updating it on a regular basis....
