Why do we blog, twitter, and otherwise syndicate our thoughts?

When you really step back to look at it, "thought syndication" is an interesting phenomenon.  It is the ultimate catharsis of a hidden human psychosis.  The fear of being forgotten.  

Really.  Why would we want to twitter every moment or blog our deepest feelings (or the antithesis of such)?  We want the world to know who we are and what we contribute to the shared human experience.  Isn't that the goal of every human?  To not be insignificant?  To make a meaningful contribution to the mortal coil we find ourselves locked in.

Or is that just people like me?  Does the "blogosphere" or the "tweets" of today represent the true heartbeat of the world?  Or does it simply represent a slightly-narcissistic, type-A, highly opinionated, extremely small group of people who have figured out how to harness an ever growing array of "publishing tools" for their ideas?  Some of us (myself completely included) have figured out how to have an idea pop into our head and have it echo from our brain to Twitter, to our Blog, to our Social Networking profile pages.  

Increasingly, I am beginning to think that our deepest fears are true.  We are alone.  We are simply speaking into the void.  Without action, all of this syndication is meaningless.  Social Network, Web 2.0, whatever buzz word you want to call it today needs to evolve and it needs to become real.
