8. Socialcast 2.0

White-label social networks—which allow businesses to slap their brands on suites of blog, wiki and other social tools—are a dime a dozen. Socialcast hopes to stand out by targeting media companies, letting users import their activities from Del.icio.us, Digg, Google Reader, Google Talk, Last.fm, LinkedIn, Reddit, Twitter, YouTube and Blog Integration into idea exchange, question-and-answer and search functions.
