Hey all, I'd like to know what your experiences are with designing online contests where site visitors get to upload/create stuff on a site (to win a prize) which is being placed in gallery and where others get to vote/rate the entries.
Some interesting questions concerning this subject are: * How do you prevent cheating with voting/rating, without making the barrier of voting to big? (or more concrete: how do you prevent that contestants aren't voting their entry to the top 10 themselves; is email validation, using an activation mail, smart or too much effort and does something like CAPTCHA <http://en.wikipedia.org/wiki/Captcha> work better?) * Which voting mechanisms work best (i.e. 'hot or not-mechanism', 5 star ranking, digg-mechanism, respect credits, etc.)? * What formulas can be used to create top 10 lists (where the amount of ratings and the average rating are being taken in consideration, i.e. somebody with 1000 votes and an average of let's say 4,1 ends up higher than somebody with 4 votes and an average of 4,5)? I've been creating quite some online contests for brands already, but every time I'm considering these (and other) questions over and over again (I don't want to name all possible questions, but just give a few to start up the discussion). Therefore I'd like to know what your experiences are and if you know some research about this. Please let me know what you think about it and see if we can come up with some good insights.
