Possible bug warning
The news article timer is buggy sometimes! When you open any recently posted article you will see "Posted just now" until the first comment arrives, but it's can be 30+ minutes old in real. The achievement is not affected by this bug, so you don't have any extra minutes, still need to open an article in 5 minutes. You can check the real posting times on community pages (Facebook, Twitter etc.).This is the newest version of this solution. If you want to read the previous full version it is still available for a few more weeks at the end of this solution.
