playBunny:I play mostly for the enjoyment of testing my skills against other players and to some extent for social interaction.  There is an egoic rush associated with a high rating, but in my saner moments I don't value that.  Of course other people do value it, but that doesn't make it important.  Importance is not purely subjective; it is an absolute truth that games and their outcomes are not important.  The most they can do is feed the ego, which is like blowing up a balloon - a biodegradable balloon!

Now, if a site is going to have a rating system, there is a certain internal logic to protecting the integrity of that system.  However, it has been demonstrated so many times that the BKR system has no integrity for reasons that have nothing to do with cheating, that it's hard to get worked up about the latter even from the standpoint of ego.
