As a slight aside, it is worth noting that there are plenty of others keeping track of their PhD studies online. Although these can be found individually (through google searches), there is one resource that brings together many PhD weblogs from many different areas. It is PhDweblogs.net, which has the advantage of being international in the sense that it has students from all over the world registered.
When time allows and once the new year has settled down a little bit, I shall include a list of thos weblogs that are perhaps worth having a look at. There doesn't seem to be much in the way of maths there, which should come as a relief to many of you.
