Had wondered about the effect on sites that require user registration to view articles.

I probably have registered at most of the main sites that want registration, but often forget the usename or password under which I had registered. Add to this fact most sites seem to “forget” who I am, and want me to login or register(!) again. Long ago I gave up - if a registration page comes up at a news site, I just go and read elsewhere.

Gary and the referenced pages have this exactly right. Have to give him credit for taking a run at enlightening the news folks. Oh well - their loss not mine, as there are plenty of other sources for news.
