Welcome. My name is John Christie and this is the second incarnation of a blog I started a while back. I created it for myself - to stay in the habit of articulating my thoughts and putting them into some coherent form. I have nothing to sell or promote. If you read them and enjoy them or in some way find them useful, more power to you. Its appearance may change from time to time, usually as a result of me screwing something up or trying to be far more clever than I actually am ... Enjoy.
