I have been a witness to a community where the player accounts are not well policed. Vendettas can become rampant. Or someone shooting for Best GM on the site will "run" a game for himself, plus sockpuppets, that then vote him, best, over and over. Not that it matters in the real world, but if that kind of activity goes on, how can you accept any sort of "Assessment" of a GM's skill from a system that allows that to happen? Finding a good game is a combination of a good team, and a good relationship. If you want to assess who someone is, talk to them, join their game, and then see how you feel about it three sessions later, like dating. If a GM is rated as "Bad", and then people see that, nobody joins their game, right? Because if you have bad and mediocre, and good, then good gets the hits and it's a popularity contest. So then you not only have the Good GMs swamped with applicants who can never be accepted, because all they are looking for is 4 or 5 people, then you have rated "Bad" gms who are stigmatized, and nobody wants to play with them as GM, and thus they never get better, because becoming a good one is a learned skill. So, that as a result also INCREASES the player to GM ratio which is already a huge problem here. Yeah, it's no fun looking for a group. It takes time. maybe days, or months. Many people want it to be easy to find a good person to marry, too. Sure you can find a one shot game. You don't have to "Marry in to" someone's campaign to play it and have fun. But you'll never know who they really are until you play with them a while, and even then, there could be all sorts of subterfuge, or it just.. works. like the real non gaming world. All of this rating, and assessing and judging is all relative, as has been said. Games I like are going to be different from some one else's. For me, I always felt it better to do the work, and find the people by applying. It gives me experience as a player, it gives the GM experience as a GM, and more games get run, rather than trying to be "Safe Bet".
