Sorry for the language in this post - the content of this is very important, and every developer of Social Software should read this CAREFULLY - not because its about google buzz (doesnt matter what social software), but because its a great real live example of what may happen, if you try to create a TRANSPARENT, OPEN system, but the access rights are not transparent ... and badly manageable!
this is a problem of ALL current social tools, including Colayer: or do you always know and are aware of, who can see what, while communicating on the layer?
>>> How can we make it everywhere and all times intuitive, who has access to what? who sees what <<<
Lets think about it & do it better in Colayer 3 Davos! - Think about it ...
