Sometimes one post (P1) is commented "possible duplicate of P2". P2 itself is commented "possible duplicate of P3".

Example:

[https://askubuntu.com/questions/246610/how-to-increase-battery-duration-hybrid-graphics-notebook][1]  

is pointed to  

[https://askubuntu.com/questions/9817/battery-drain-on-ubuntu-is-fast][2],  

which is a possible duplicate of  

[https://askubuntu.com/questions/400/tips-to-extend-battery-life-for-laptops-and-notebooks][3]. 

What can/should we do to improve the situation?
