I don't like the font either - far too fussy and twee, and old-fashioned!
I prefer Mumsnet layout, with threads labelled "Started by" and "Latest", which gives an idea of the time-span of a thread. I would also like to see OP's posts highlighted (I notice only the opening post is highlighted but not the following posts in the new version), and my own in a different colour, which is not the case on the desk-top site at the moment.
Sometimes on a long thread I just want to skim-read and find the OP's posts, but that's not easy to do unless they are highlighted.
Not bothered by an edit button (MN doesn't have one), and I always preview before posting.
