I think that the problem with Wave's scrollbars wasn't so much that they were bad, they were non-standard. Scrollbars are OS territory, individual webapps should probably not try to reinvent them. (I would argue that they should only ever try to reinvent them when they provide something substantially better and when the standard OS implementation is lacking.)

My problem with wave’s scrollbars was that whatever code they had to do scrolling was dramatically slower and glitchier than native scrollbars.
