Competitions

Polls are not the alternative of competitions, both are different things.

It would be good if you can explain why its good. Having competition would make developers aware about how to write effective code.- just a thought.

Am not sure also I don't believe this platform is made for such things. But we can use as knowledge sharing instead of a competition. Am not sure how competition make developer to write effective code. We do have forums, interview sections etc. But still let Admin decide on the same.

I have observed on multiple forums (programming competition that having challenged developers would result the best of the programming languages). Take a look at Programming and Puzzle section here. http://codegolf.stackexchange.com/. Not only it will result in knowledge sharing but having effective piece of codes will raise the fame of this community to next level. - Just a thought.
