mirror vs diamond..

This is an article that follows up a previous post I had added on online identities.
As you have seen from previous posts here at ihopto we feel that a TAG can give you an online identity.
These articles raise an increasing isssue on who you are on the internet. I like the theme from this article that "facebook treats our identity as a mirror - they assume we want to reveal everything, while we really are a diamond with multi facets" . Although I would argue that now with the "categorisation" of friends that came with the new upgrade of facebook means that your post and updates can effectively be segmented. I guess they have sort of recognised this issue.
Our idea is for users to use different TAGs for different links. One TAG for the sites you want to share with friends, another TAG for those sites you want to show with family, and another for professional sites etc..
