I don’t need post titles. I had no idea. I just forgot to give the last post a title, yet it shows up just fine. I don’t think it’s ever occurred to me, in however many years of using WordPress, to not give something a post title. On the admin screen, it’s got “(no title)” and then a numerical slug. So I guess it works. I’m not sure if it would have made a difference when I started Summing-Up, but it seems like something I might have liked to play with.
