The way to improve the board is to make constructive posts about the company and put the idiots on ignore.  By constructive I mean discussing and analyzing news and information gleaned from sources you can name or link to.  By idiot, I mean the mindless management bashing with little or no actual information.  I don't mind someone saying they don't believe in management as long as they can put together a coherent argument for it.  And to the dufus who thinks you can post anything you want on a board, it's not a bull***t board, it's a bulletin board.  I use (and I encourage others to use) the ignore feature liberally to improve the signal to noise ratio.
