I suspect a bug. I have no recollection of turning personal blog posts on, but I still see the tag on next to Latest. It’s entirely possible that I forgot about this, but that doesn’t sound like a thing I’d do.
(That said, just realizing I can set a personal blog post penalty of −25 is going to make LessWrong much more tolerable.)
I don’t think an oops is necessary here in this case (beyond just not crossing the norm again), but this is still appreciated. Thank you.
