Thank you for the reply Andrew. A great update. I'd love it if you could work full time on this for a while.
At a cursory glance you have all the issues I think are generally regarded as important here: edit in place, private reply, accessibility, reporting, anon posts, role playing (I'd love to be able to do De Bono's hats!!) etc.
As to the roadmap. It may be more consistent, but deleting all the links to discussion pages and tracker items has made the it much much less helpful and useful.
