Gee, where do I start?
Some of the Seasons contests were raffles - and they were the ones I thought rewarded entrants best for their efforts.
Getting people to share their love of the uke and their joy in music is not "having others do work for you".
MUSIC is not boxing, world championship wrestling, car racing, the olympics, the tour de France (although they often share the drug thing), marbles, 10 pin bowling, arm wrestling, etc.
Defeating an opposition is not something that I set about to do when posting videos in a "competition" here and I'm a pretty competitive person.
And the notion of having to be awarded a "tangible prize"? Is that really why people enter comps here?
If the entries are to be judged the presentation should go, "I liked this one best."
Or, "The point system used shows that the judges preferred this entry."
Or, "All (or some of) the entries went in a hat and ..."
NOT "THE WINNER IS!"
Just my 2 cents worth.
