Why blog ?

Things have been rather quiet at work for a while. So I started looking around, and read a few blogs. When I did, I realised that a lot is being said that is close to my heart, and/or needs to be said. And a number of well known people are saying stuff that I thought was not relevant to people outside my context.
Now that I know that my troubles (and my ideas ) are not mine alone, I'm going to talk about them!
