Blog Policies.
I've set up this blog for myself, as a commonplace book, with the idea that it might also be useful for outside readers. That is why the topics are idiosyncratic. I see that most of my readers are directed here by Google searching rather than being regular readers.
I will delete rude comments, and will give less leeway to anonymous comments than to signed ones. I will for now at least allow stupid and ill-informed comments, though other readers don't enjoy them unless they are so ignorant as to be funny.
I will revise my posts freely, usually without any note that they've been revised. If I make an important mistake in a post that I think people might refer to, I will note the mistake and correction. But I'm not trying to make this a historical record. In fact, I'd like to merge posts on the same topic and delete posts not of interest a year later, except that I never get round to doing that.
