This is the biggest take from me too. I know the founding fathers of Totallympics Song Contests are way more traditionalist (and stubborn) than the IOC and FIFA combined , but i think it's time to make some changes to the show. Mainly the schedule for the Grand Finale
It's evident, that Saturdays aren't the most suitable time for a growing number of people, who are doing lots of other stuff. Switching to Sundays could help free more people, as that is the more traditional rest day for everyone.
Also, another good idea in my opinion is to split the Finale into 2 parts. Have half the votes on Saturday evening (European time) and the other half on Sunday evening. This way users could choose, which of the 2 days is more suitable for them and we are getting away from the day sessions, when people are more likely to be outside, working, travelling, shopping or doing other things, that they wont do in the evening. The downside to this is the time zone difference for our Asian users and Wanderer. But we could make a special session just for them on Sunday afternoon, which would be Sunday evening for them, or they could be the first to vote on Saturday afternoon etc.
There needs to be a change, so that more people follow and participate, because having the host submit 20-25 from the 35 nations is a bit underwhelming.
