I never signed up for the 7 day trial (accidentally or otherwise). SA just assigned it to me and after 7 days I also cannot read anything. I've been using SA for at least 10 years as well...

The change to narrow the column width has made reading the articles more difficult.  In addition to more down scrolling, the authors' tables more often are not fully visible and require sideways scrolling.  This change was uncalled for and makes SA less usable. 

I really HATE the revamped comments stream format. I want to see all previous comments and the "load more" concept is nonsense.  I also dislike the bolded text for the current comment the site happens to think I'm reading.
