Why blog?

There are numerous reasons to why I started blogging. But why blog?
Is it not just a symptom of our present culture where everybody wants to expose themself? Am I blogging because I am a kind of exhibitionist - only not physically but rather a mental exhibitionist? I want to expose my thoughts to the world, look at me, look at what I'm thinking?
The answer is NO.
I'm blogging to keep my head from exploding.
My mind is so full of thoughts. And paradoxically, this actually to some degree prevents my work from progressing. I get mentally constipated. More and more is constantly generated but it goes no where.
By blogging, I can let it out in a media where I do not have to reflect on form first, but can let it flow directly from the mind to the writing fingertips. Unedited.
I hope that blogging keeps my writing flowing and that the natural flow of words - from mind through fingers to screen - will transmit to my research work as well.
That I will learn to stop editing while I write (a very destructive procedure) and save the editorial process for later. I believe the blogging will help me to become more productive. Even though at first hand you might say it is taking extra time - that I might have used for my research instead.
Rather than imposing my thoughts on anybody I am hereby sharing them with those that may care to read it and perhaps share my interests, thoughts, ideas. Or disagree. And hopefully contribute with interesting comments.
A blog is a great media for transforming an unedited random monologue into an interesting dialogue.
So feel free to comment - I'm grateful for your contribution to transforming this now monologue into a dialogue.
And prevent my head from exploding.
