Palo Alto, Calif. - Online social network Facebook this weekend quietly launched a new chat feature, which the company plans to roll out gradually to its 69 million users this week. The IM application at launch does not support third-party services like AIM, Yahoo IM or Google Talk, but the company plans to integrate members' notifications into the Chat bar, and Mini-Feed activity will also appear in IM conversations as it occurs.
