Austin-based Pluck announced that it has signed a deal with Hearst digital. The Pluck social media technology will power the audience participation and community features of the websites of some pretty major Hearst brands including Cosmopolitan, Good Housekeeping, and Harper’s Bazaar. Alex Ballantyne, Hearst digital’s Managing Director, says: “Based on our review, no other social media platform can scale to support traffic volumes in the millions like Pluck SiteLife. In addition, the integration of the platform across the many facets of social media, such as blogs, ratings, photos and comments, can help us ensure the experience for our visitors can be one of the best available on the web.”

Dave Panos, CEO of Pluck, noted: “Powering some of the most popular sites in Europe, Hearst digital is a leader in attracting readers from across the web. Working together, we can help Hearst digital empower its readers with a fully-interactive and social experience designed to let readers contribute to site content and participate with editorial staff, as well as other readers.”

With approximately $10M in 2007 revenues, Pluck was reported to be for sale for $75M. This deal follows another significant new relationship with The Guardian announced last month.
