I was catching up on some blogs, adding a few to the blogroll, etc., and I had probably five or six blogs open at once on my screen.
I made a comment, and a rather long one at that, on one blog. I hit "post," closed the comment box, and that was that.
But I think I commented on the wrong blog. I closed all of the blogs several minutes later and found an open comment box--the one I'd meant to write in--remaining.
I went back to the blog where I thought I'd commented, and there was no comment there.
So, if I've written a completely random and off-topic comment on your blog, now you know why. Of course, I've written completely random comments before, but I do generally stay on topic.
Not this time.
