Ahead of next week I am checking out previous posts from the official #mtw3 blog. On this blog I will be including much material that is not really part of the main event. Linda Shelton will probably stick to the essential outline.
On this post from earlier in the year there is a photo of Sally Potter on a visit to Second Life. Most of the avatars I know are usually in Twinity. I notice Web Kirby has started to comment on Facebook.
I think #mtw3 is mostly headed for LinkedIn. But Second Life has some activity and may turn up again.
