Last week I had a visug session at Microsoft Belgium with Scott Hanselman.
He said, every developer needs a blog, because it will help you later to find the answer immediately.

I have a blog, but I'm not really using it. So I will write more posts in the future. 
 

When you don't have a blog right now or haven't seen the following video, then you really have to watch it.
