   Highlight original poster replies
  It would be nice to highlight OP replies in threads to have a quick overview of the thread.   
  Actually what would be better would be to highlight replies that actually provide answers or support to the OPs topic   ;  Maybe different background colors:- OP posts- useful replies- Reader replies-...   ;  Maybe a highlight color for OP, and a "usefulness" bar that has good visibility so that people can identify useful posts, but which is less intrusive than a highlight color.Then, usefulness could eventually tie into user ratings (if they post lots of useful comments, etc).
