liquid threads becomes really annoying for long discussions
We've got some updates in the pipeline that will make things more linear and easy to follow. I'm hoping to be able to stick them on this wiki in the next few days/weeks.
Sounds good. From a usability perspective, the "new post" thing isn't obvious. Even a little "[NEW!]" would be helpful to complement the highlight, if you can't make the highlight more obvious.
I also think you should hide the "Link to" behind "More"... but reveal the "edit" button. I think that would reflect what people more commonly need to do.
