I considered simply not addressing my long absence at all. But it seemed likely people would wonder why I would have been gone for so long from a blog I myself created. Yet, the reasons for my absence are not particularly interesting, and do not have anything to do with the topic of this blog. So with this post, I acknowledge my absence, and register an intention not to let there be so long an absence again. If anyone really wants to know what happened, they can contact me privately. But fair warning: the response will be boring.
