If you hadn't noticed, I changed the theme of the blog.  This also involved a change of the engine from BlogEngine.NET to DasBlog.  I used to use DasBlog years ago, but felt it lacked in features as others were innovating faster.  About a 6 months ago I moved over to BlogEngine.NET as I thought it was the most feature capable at the time (I as already not using DasBlog for quite a while).  With the use of a Mac as my primary computer, and with trying to find a good blog client, I found that I was experiencing many small problems with BlogEngine.NET, so I looked around and found out that DasBlog had really evolved to appear to be the best self hosted engine available (at least for on .NET servers). 

And hence the flip-flop / churn.  And I REALLY like this theme.
