@techscorpion I think it’s 3 as well as the opportunity to pitch an idea without getting responses from[ commenters that in the end contribute nothing constructive to the conversation] (2d/3d ‘Jigsaw’ Puzzles - Shapeymix) (thanks @lordbanks and @Ubarab for being the exceptions). People will check out the sites that are interesting to them even if they don’t publicly acknowledge/vote for them, and the competition post shows that people are brimming with ideas but there is still a dearth of viable outlets for these ideas to be shared.
There may be a future post about how to improve the competition, but I’ll just mention something. The OP of the competition post shared a clear format, and it would have been easy for some people to add a video description or a screenshot to the pitch, and so it should have been made clear whether or not such things were allowed, because it gives some people a clear or subconscious advantage. Most people followed the format though. The competition itself is a prototype/version 1 so if the organisers decide to run another one (hard to say since the Battlefield is still pending about 2/3? years later) then some improvements can be implemented. Another way the voting could be improved is that each person gets 1-3 max votes. Weighted votes: members 50%; judges/organisers: 50%;
Disclosure: I sent a pitch. I made these comments so that people can have a level playing field. I would still speak as freely had I not sent one.
