WEEI.com today announced it has reached a content sharing partnership with SB Nation that will integrate content from the nation’s fastest growing online sports network with WEEI.com’s premier local coverage. The new agreement will enhance the experience for users of WEEI.com by providing fans with relevant content and national & regional points of views on sports news. The partnership also makes WEEI.com the exclusive in-market content partner for SB Nation and its network of over 300 online fan communities.So this is pretty cool. Yesterday, SB Nation and WEEI.com announced a content sharing agreement. The short version is EEI and SB Nation Boston sites like BC Interruption will trade links and promote each other. That'll be easy for us considering we are linking to EEI's The BC Blog quite a bit already.
