Today we unveiled a new interface for making listings more social. We’ve always believed that listings are a form of conversation. As social networks open up, we can now make this even more true.

When you post a listing through Oodle, they not only appear in over 200 Oodle powered marketplaces (including Oodle.com and Facebook Marketplace) – they are published in your social streams on Facebook, MySpace and Twitter giving your friends and followers the scoop on what you’re selling or what you’re looking for.

As users “connect” with Facebook, MySpace and Twitter, your identity on Oodle also evolves. Your public identity on these social networks becomes tied to your listings. People get to see the person behind the listings before choosing to meet them, providing a cleaner-well-lit environment to make a handshake.

Users checking out listings also benefit. They can solicit their social networks for trusted advice and recommendations. For instance, when viewing a job listing — “anyone know someone that works here?” — or a rental listing — “is this a great neighborhood?”
