When OpenSky launched a year ago, it was a commerce platform for influential bloggers . Bloggers with a following would curate their own merchandise, OpenSky would source the goods from manufacturers, and split the profits with the bloggers. It sounded a hell of a lot better than the miniscule affiliate fees most bloggers were used to, but it didn't work out. It never got past 5,000 bloggers with a reach of 100,000 unique visitors. "Mixing content and commerce was confusing to people," says CEO John Caplan. By November of last year, Caplan decided to start over with a slightly different concept, which OpenSky has been testing since January, and opened up in April. Instead of being distributed across 5,000 blogs, OpenSky is now "a social network for commerce." With no marketing, in the space of a few weeks, OpenSky is now up to 200,000 members and one million unique visitors. And with only 50 curators instead of 5,000, it is selling hundreds of thousands of dollars worth of goods every week. Caplan refers to it as "Twitter meets HSN."
