On blogging and status updates

This is my return to blogging, but this time hopefully it will be about something substantial.  You see the first time I had a blog, I was a young and stupid kid who complained about how much life sucked and troubles with girls.  This time around I will bring to this blog, not really deep thoughts, but hopefully something more than "why doesn't *insert name here* like me, and "why would she do that..blah blah blah".  I am not saying that I will not ever talk about the current relationships in my life, but that there will be more to read about in this blog than just that.  So here we go.

I was thinking earlier tonight, why do I feel the need to update my status on various outlets, ie facebook, twitter, etc.  How did I get to a point, where I spend a large amount of time reading through what people are doing or feeling.  I probably don't even talk to half of the people, or even know them personally but for some reason here i am reading that, John just had a bowl of chili for lunch, or that Jane is tired from her trip to LA.  Its very seldom that I talk to these people about their status, so I don't know why I invest so much of my time in reading them.  Does anyone spend time reading about my daily or even hourly status updates.  I would hope not because i live a very plain life, but at the same time, by updating my status, it inherently means that i do hope someone is spending a few moments to check my status.  I don't know, this probably requires a little more thought, I just needed to write it down so I can come back to it later.  

What do you think, do you have an opinion on status updates and why do you update your status?
