I think the entire thing can be summed up by saying most long time newsgroup users started out on NNTP (when it was the only choice) and never moved to HTML since NNTP is generally ASCII based (faster), there is no login, no advertising, it's much quicker to switch from group to group, view unread messages, highlight your own messages, etc. etc.
Some of us will drop and others will migrate. In the end, I doubt any change will be noticed.
We all survived the change in plotting in 2000, the CUI in 2006 and most recently, the Ribbon. I'm sure we'll survive this also.
