This just happened today -- Charlotte.com used to take you to the Charlotte Observer web site. Now it takes you to a separate site full of blogs, Facebook, and Twitter stuff. If you want the newspaper site, you have to go to CharlotteObserver.com.
Sure enough: I went to http://www.charlotte.com/ and got a web page including a pop up with this message:
Expecting to see The Charlotte Observer? We're still here, but you will need to update your bookmark to CharlotteObserver.com.
Here at Charlotte.com, the Observer is supplementing our community coverage by including even more about Charlotte. Customize area information to fit your specific interests, see what your friends are talking about, and find out what other Charlotteans think are the most popular topics in the region.
Log in with an account you probably already have, like Facebook, Google or Yahoo!. You're one click away!
