"changeable pseudonymous identities" have their place on the internet, in chat rooms, on blogs, throw away accounts on reddit, etc. But imagine how much "spam" is accumulated by allowing something like this to occur. Our identities right now are facebook profiles and twitter accounts, connections being friends or those we follow or are followers of. What do we do with them? Post ramblings of what is happening in our daily lives, tweeting about the something that people may interesting. Millions of us using all this technology for something that amounts to nothing but keeping ourselves amused. Think of what we could actually do. I am not righteous by any means or a do gooder, but with all the connections we form, the groups, the followers, the friends, the masses that flock to whats cool, couldn't it all be geared towards helping people?
