On the Second Life wiki 3.6.6 Map File page it appears that Facebook integration will be scheduled to be released into the SL Viewer 3.6.6 next week. This will be big news for sure to post to Facebook from Second Life. As many know already snapshots/text can be shared with the online SL web profiles and Snapzilla.
The official Second Life Facebook page now has 320,414 likes/fans so perhaps its time to go more mainstream into the SL viewer. In the near future it would be good perhaps to have Plurk, Twitter & Google+ to be integrated into the SL viewer.
Second Life Share Coming Soon
The Post to Facebook window is part of the Second Life Share feature, which allows you to post to Facebook from Second Life. Second Life Share is an opt-in feature that requires your permission before sharing any information with Facebook. For more information, see Second Life Share in the Second Life Knowledge Base.
Check out Viewerhelp:Post to Facebook for more details about this upcoming feature. Will you be using this new Second Life Share feature next week ?
