VentureWire did a full write-up about Rapleaf today … unfortunately, i have no link to the full story (you need a subscription). but here is a quick quote:

The company is working with 46 various online ecommerce companies and Web sites to integrate Rapleaf’s technology. Rightcart.com and online classifieds site Edgeio.com are two of the start-ups that Rapleaf is working with currently. The market for portable ratings will likely continue to grow, especially as giants like Google Inc. launch their own marketplaces.

Hoffman said that he doesn’t view eBay as a competitor. “The people we are helping may be people that compete with eBay, but we don’t,” he said. “We are focused on classifieds sites and sites like Craigslist.org.”
