I've neglected my learning log over the last week. To be quit frank, it was because I did not really learn much worth talking about. Of cause, I had a look at some books on architecture to get the spelling (of the names mentioned in) for our first comments concerning the expert groups right. Doing that I got carried away by some chapter that was not related to our topic at all, as it usually happens to me. Nevertheless I published our comment yesterday. We don not have a provoking thesis yet; I is still to come.
