Sometimes I notice answers that would put heavy load on a server or are not at all best practise.
Object saves / loads in for loops.
Loading JQuery in Magento because it is "easier".
Nested ifs and loops.
Using rewrites when an observer is easily useable.
Because i do not know how to respond to it I have left a comment last time. My question is should we flag stuff like this to watch over the quality of the answers?
