Very True. Most of the tech groups are gone now. Example If you want CDr or DVd help you have to find a web forum. All the pros have left usenet.
RW has become a chat group for a few old timers. Many newbies are either dissed or ignored.
I doubt anything can save usenet. Like Rome, the unwashed hoards are at the gate, over the gate, and in our yards. All the filters in the world can't beat them back.
