Who's that hiding behind a photo & words?

I was sitting here... admittedly scrolling through the Facebook feed...when it hit me.  Someone should do a psychological study on why and how we chose our Facebook profile pictures.  I think there could be some serious findings discovered that could clue us into how we view ourselves and how we think we can change how others view us.

Wrap your brain around that last sentence.  I know I'm trying to.

What I'm getting at is this: How are we trying to show (or maybe prove) to people who we are - whether that be through our profile picture, a well placed status, or possibly our profile information? 

There used to be days when people had to sit down with you and have a conversation to get to know you.  Now, they can just "Facebook stalk" you and discover your favorite quotes, random inside jokes no one else understands, and hilarious pictures of you and your cat.

Don't get me wrong here, I'm not speaking out against Facebook - I'm still a user - but I do have to ask myself, who do I say I am through my Facebook? 

Who do you say you are?  Is it really you?  Why do you portray yourself the way you do?

I'll think more about this and hopefully post more later, but I did want to bring it up because it's an important thing.  I think we can tend to hid behind a computer, creating who we want to be, when in reality it's just a facade.

What are your thoughts on this?
