The need to express ourselfs

During the last couple of weeks we've been talking about things like rss flows, twittr, blogs and so on. There are infinite ways of expressing yourself today. We can let the whole world know how we're feeling. Right now. And the need for doing so seems endless. We want everyone know what we love and hate. If we're happy or sad. If we feel inspired or empty. All of these emotions and feelings we publish on our blogs, twittrs, facebooks and myspaces are in a lot of ways expressed in a one way communication. We just send our messages out there without the need of response. I went in on twistori today and watched it for a while. It is amazing how many people there are that have so much on their mind.
It has also opened up the space for expressing your opinions och discuss thing you believe is important. Before all this, the only once who really where entitled to express opinions in the public space was journalists. Today that space is open for everyone, so you could argue that blogs and such really makes it more equal when it comes to expressing opinions. Internet doesn't judge if your educated or not, if you're a man or a woman, if you're black or white or whether you're young or old. And there is no limit.
What I'm trying to get at here is whether we have more urge to express our opinions today and therefor created the opportunity for it or the opportunity to express yourself at all times have created the urge to do so? I'm not sure but I I do believe that it has created a more balanced forum where everyone can reach out to a big audience if they fell they've got something on their mind.
