Why am I writing this blog?

Okay, most of my writing 'til now has been in the form of journals, which are supposed to be read only by me.  Sometimes a sneaky girlfriend will intrude on my private ramblings, and then we'll fight and cry. 
Because she misinterprets what I write.  Because that stuff isn't meant to be read by anyone else but me, so I don't feel the need to explain things.  It's almost like a secret code, right?, and someone else who reads it might THINK they understand what it's saying, but really they don't, because they're not me, and they don't know the code. 
And it's probably fool-hardy of me to take this same attitude into this potentially-very-public blog.  But my instinct is just to go with the flow and let it all hang out. 
I have beside my bed a book called The Hacker Ethic, which I want to get around to reading, because I think it will help me clarify my position on privacy and freedom of information and keeping secrets (such as business plans).  And maybe it will help me come to a decision on how to treat this blog, which at the moment is proceeding willy-nilly. 
Ultimately, I want to use it to share ideas on politics and spirituality and technology and humor and emerging media, but for the moment I'm still trying to wrap my mind around the simple concept of the Blog. 
(What a horrible word, by the way.  It's the sound of vomiting.  I said I wasn't going to use it anymore, but I'm not as consistent as I could be.)
Okay, so why am I writing this LOG?  I am writing it for myself, Foodie Figtree, delver into this mystery we call life.  Because I enjoy typing and watching my words appear magically on the screen.
But there has to be more to it than that if I'm to continue, because I can type and watch my words appear magically on the screen without sending them out for everyone to look at.
So maybe it's a sense of danger that compels me to continue.  Because it seems likely, based on my experience, that these LOG entries will come back to haunt me, that people will use them against me somehow.  Or maybe I'm just paranoid. 
Maybe I think there's value in exposing the flaws in my thinking and judgement.  Maybe someone can benefit from seeing my insecurity and confusion.  Maybe it's just more compelling for a reader: a crazy, un-polished, unpredictable flow. 
Anyhoo, I doubt that this LOG will harm anyone besides myself, and I affirm that I'm aware enough not to write anything in this LOG that will harm myself, so there, let's be done with that train of thought.
Oh, yes, the big reason I'm writing this LOG:  when strong artificial intelligence comes around, say in the next 20 years or so (if it's not here already!), it will have this record of my output; and hopefully this will be a basis for it to give me preferential treatment.  Like, say, maybe I want some resources to make an art project, and I don't know where to go to get the resources, and then some sweet AI (let's call it the Void, just for fun) will decide to pop those resources into my life.  And I'll say to myself, Gosh, I'm glad I decided to write that LOG so long ago, otherwise I'd be dead.
Yes, having said that, you must now suspect that I will represent myself unrealistically on this LOG, playing up my nice qualities, and ignoring my ugly traits.  But I'll bet I'm leaving such a trail of digital information (about my purchases, my travel, my online activity, etc.) that an AI will be able to form a more complete picture of me than what this simpe LOG is painting. 
Hm, I guess that's some FOOD FOR THOUGHT.
