Nigel, I think you keep the balance fairly, and the vitality of SZ is proof of that. One suggestion I would make is please don't display that someone has edited their post, especially if they edit it on the same day as they posted--which is usually for the reason of spelling and/or grammar corrections, or adding/deleting some ideas for better clarity.
It's unnecessary to show it's been edited and prejudices the reader.
