Of course, plus the rank system, (where the best answers appears 
first), you "almost" have a winner.

I said "almost", because I've seen answers that were classified 
("despite working") above other better or optmized answers 
because of the date they were posted.

IMHO maybe in programming side, it would be nice to have an 
additional technical vote walking together with rank system.
