I managed to get the domain redirected and have dropped posterous and returned, entirely, to Blogger.com. All links — scottpaterson.org and www.scottpaterson.org — should point to here now. From a reader's standpoint (all two or three of you) this should be transparent.
Over the next little while, I'll probably play around with the different templates to find a look that I like.
I have also linked this blog to my Google+ profile.
