One of the reasons for this is that I'm short of time so anything that acts as a disincentive means that the updates don't get done.
Well the Blogger interface has certainly been acting as a disincentive. It is particularly poor at uploading photos and videos in a timely fashion in the evening (which is when I do most of my entries)
So I'm giving Wordpress a go. The new blog is at http://www.rgbracer.com
Plus the Apple template is a bit cleaner and nicer, with a better blog search facility.
Sorry for being a pain, but hopefully you may get more frequent updates as a result.
