Don't piss me off, waste my time, post SPAM, post shit, or anything I deem annoying. If moderating comments turns back into an exercise in frustration, I will just hide all the comments, and the comment form, again.
I am not a public utility. You think you have something to say, click the link in the top right corner that says "Create Blog," and have at it. Blogger is free, as is Wordpress.com. I do this for free, which means that when I stop getting any benefit from it, I stop doing it.
