What's the difference between Programmers and SO
Why does this site exist when there is Stack overflow already?!!
This site is for more subjective questions than SO is for. SO is mostly about getting help, or a direct answer, for programming questions while this place has more argumentive answers.
So we can ask questions like https://softwareengineering.stackexchange.com/questions/35887/why-programmers-when-stackoverflow-already-exists
