Well, I finally got fed up trying to customise my WordPress blog. All that PHP doesn't make sense to me. So I looked around for a .NET blog and decided upon BlogEngine.NET. It's written in ASP.NET 2.0 so there are features I understand like masterpages and user controls. Also it all runs from XML files so there's no need to have a database. I've been playing around with it for a while and am going to customise the current theme quite a bit more by the end.
