Pop culture-focused social media site Buzznet, which claims more than 6 million users, has closed a $6 million round of financing led by Redpoint Ventures and previous investor Anthem Venture Partners. The site’s primary focus is on music and offers related blogs, videos, photo-sharing and band-related features. In particular, Buzznet has struck alliances with indie bands by promoting specific online community channels for them. The company has also been working with established popstars, like Avril Lavigne, who earlier this month set up a merchandising line and contest with Buzznet. Release.
