It has nothing to do with the name. The issue is very basic, and comes from a misunderstanding of what a game jam is. Game jam's is NOT about ME, but about US. 'Rate for rate'-post is all about getting people to play MY game, and not about playing or rating other peoples games. I think often we forget the community aspect for a game JAM, and instead we see it as a place to self promote what we are doing.
The sad part of this is that the best part of the game jams is not making the games, but it is share them with others, and seeing what others has done.
