I think this shows that there is a large audience for games involving simple voting (eg: Nintendo's old "everybody votes" from the Wii, 1 Vs 100 from Xbox 360...).
Even if applied to a regular game like Pokemon, the audience splits into groups and tries to push for their ideals. I almost want to say it's a society simulation tool more than a game. I imagine that many more games could be created like this, the input improved so that the game input commands can be separated from the regular chat messages. It's kind of like being able to control what your sports team is doing from the crowd during a match, and I think it also reinforces the idea that every single person makes a difference.
Although, it was originally started as a "I wonder if anyone would like this" I'm sure
