Google to announce a preview release of Friend Connect, a new service which will allow any site to provide social features by tapping into existing social connections. Sound like more Google junk to add to the sidebar! First it was Google Social Graph, and now Google Friend Connect.

“Google Friend Connect is about helping the ‘long tail’ of sites become more social,” said David Glazer, a director of engineering at Google. “Many sites aren’t explicitly social and don’t necessarily want to be social networks, but they still benefit from letting their visitors interact with each other. That used to be hard. Fortunately, there’s an emerging wave of social standards — OpenID, OAuth, OpenSocial, and the data access APIs published by Facebook, Google, MySpace, and others. Google Friend Connect builds on these standards to let people easily connect with their friends, wherever they are on the web, making ‘any app, any site, any friends’ a reality.”

It does not look like Google has go the right Social networking service yet, but let’s see what Friend Connect brings and how it fares.
