A great article, I just passed this onto a workfellow who was doing a little analysis on this. And he in fact bought me dinner because I discovered it for him... :).. So let me reword that: Thnkx for the treat! But yeah Thnx for spending the time to talk about this, I feel strongly about it and love learning more on this topic. If possible, as you become expertise, would you mind updating your blog with more information? It is very helpful for me. Big thumb up for this blog post!
