A little worrying!
The author of this article claims that a website was built for him from elements found on the internet, the site then contacted his friends and started inviting them to join and make a social network.
He raises the question “Who owns your friendships?”
Once you have ‘friends’ (say via Bebo) is this relationship then ‘public domain’?
The other articles on the blog are serious and well considered, it seems fairly authentic. Worth a look.
