You could not leave well enough alone. The old was better by far. At least give us the opportunity to chose if we want to switch.
Go back it was much better.
Until Yahoo fixes this Yahoocare mess, open http://ca.my.yahoo.com, bookmark it and log-in. In my case, all of my content is the same as it was in the prior U.S. version, including layout, themes, weather locations, market summary, portfolio cumulative totals, company news, etc. In other words, Yahoo has not changed the Canadian version of My Yahoo. You cannot add new U.S. content, but at least you can get back to what you had.
