Niche social networking sites are starting to grow such as JockTalk co-launched by retired and former Major League Baseball Player Shawn Green. The new site combines profile pages, back-and-forth conversations, and original sports content. JockTalk is debuting with 60 athletes on board, including representatives from the NHL, NFL, NBA, MLB and the Olympics, to name a few. The network isn’t just targeting players and fans, however; the team thinks it also has the right mix to appeal to sports publishers, marketers and leagues and teams, too. It includes monetization options that intend to take advantage of those possible connections, too, including an e-commerce platform for selling tickets and merchandise. Revenue will also be derived from advertising and content syndication. With lots of sports sites online, can JockTalk succeed? Remains to be seen.
