I think the biggest issue I have on this forum is the occasional errors, such as the "last 25 seconds IP post". Other than that, my experience is quite similar. I'm fine with UI as long as the UX is good. For example, even if the quick reply feature is quite basic, I can work with that as long as previewing the post or posting my reply doesn't lead me to the homepage or somewhere else. Adding more quick-access features would be great though, because someone might find remembering bbcode tags difficult. I guess the preview is there for that purpose, but it would be cool to see a toggle right on the quick reply box.
