A well written article, I just given this onto a colleague who was doing a little analysis on this. And he in fact purchased me dinner because I found it for him. :). So let me rephrase that: Thnkx for the treat! But yeah Thank you for taking the time to discuss this, I feel strongly about it and love reading more on this topic. If possible, as you gain expertise, would you mind updating your blog with more information? It is very helpful for me. Big thumb up for this article!
