After a few months in a closed beta, Google launches a new service targeted at webmasters that want to profit on the wave of social services.
With Google friend connect, you can also create a web site that has features similar to Facebook or Orkut. The objective is to let users join your website with the same login used in other networks. Then, they will be able to connect with friends as usual.
I think it is a smart service, which can improve many web sites. You should take a look at the original posting at the Official Google Blog (Google Friend Connect now available).
