WordPress is a great service. But running as part of wordpress.com hosted solutions had a price. Not a cost (the service is free), but the price of limited flexibility and inability to tinker.
So I have moved to my own domain and will continue with the new blog there. All posts from this blog have been migrated across, though unfortunately not comments. Maybe later I will figure out how to do that, that will be part of the experimenting I wanted to do.
The learning never stops, it just moves on to the better pastures.
