Why do I blog?

I just caught myself writing something strange.
In an answer to some one who had commented on one of my drawings I said that I might try some technique that might improve my drawing skills but that I had to think about the impact it would have on my blog.
The strange thing being that my blog is about me learning how to draw. So every thing that could improve my drawings and drawing skills should be more important then my blog.
My feeling that the blog is more important then learning how to draw got me thinking about why I blog.

When I started blogging I had a few reasons:

• Because I like to write.
• Because I like to draw.
• Because it feels useless to write when no one is reading your work.
• Because it gives me a public forum to show my drawings.
• Because I can get all those cool statistics about the amount of people that read my blog and my RSS feed

Now I’ve been blogging for a while I’m finding even more important reasons to keep doing it:

• Because it helps me to take some distance from my drawings and look at them through the eyes of some one else.
• Having to write an article about some problem means that I have to think it all the way through instead being content with a half as solution
• Because I get to meet a lot of nice people who are enthusiastic about the things I write about.
• In writing about autism I can some times answer question people might have.
• In writing about autism I can, hopefully, show people that we are not pathetic disabled people who need your help but independent proud people who do things in our own way.
• Because it helps me to meet people who point me in new directions.
• Because it’s turning out to be a great tool for growth and self improvement.

(Maybe some one can tell me if a “half as solution” is a decant thing to say?
I hear it a lot on TV but it’s never clear whether you can use it in any conversation or not. To my Dutch ears it sounds a bit off.)
