I was actually interested in and reading this thread until the cat pictures appeared and once again a thread goes astray. I don't understand why some folks feel the need to post them in a thread where they haven't offered a single comment beforehand in regards to what's being discussed. It is childish. If you had no interest in what was being discussed then move on. I have nothing against cats, owning two of them myself, but I am pretty tired of seeing them needlessly in a serious discussion. I came back today to see if the thread had gotten back on topic but I see it's gone the way of many others.

Sorry, tainted-heart, the topic was a good one while it lasted.
