A few days ago I commented about how an HN title had made me expect that the Amazon 3D printing store was 3D printing as a service, which alas, it is not. The mods changed the title, which in that case made it less misleading, but they didn't leave any comment to say what the old title was. My comment no longer made any sense, and because a few hours had passed, I couldn't edit it to add a footnote for confused readers (and plus, I couldn't remember the precise wording of the original title). I can understand why the titles are sometimes changed and most of the time I think it's for the better (although this time I agree it was a bad choice). What I would like to see added is a changelog feature, so that whenever the mods change a title, a footnote appears directly below the summary, before comments, showing who changed the title, what it had been, and optionally the reason it was changed.
