You read it here first ... BlogHer LLC is launching the BlogHer Advertising Network for women bloggers June 1 with 25 parenting bloggers and new Sweet Simplicity Sweetener as the featured advertiser. Other advertisers will be added in June and July. Plans call for additional contextual categories over the next two quarters, starting with food. Participating bloggers agree that BlogHer will provide the only graphic media advertising on their blogs. They keep their own urls, traffic and communities but agree to publish by editorial guidelines. BlogHer, co-founded by Elisa Camahort, Lisa Stone and Jory Des Jardins, started as a conference last year and has grown into a full-fledged community that tracks and promotes blogs by women aided by volunteer editors; ads will start appearing on the community site but participation the ad network is voluntary. It’s also limited for now.
