Hi all,
As this topic is quite meaty it is probably better if I respond to general points as opposed to posts.
Firstly, the claim that the system is elitist. Indeed it is. However, how is this a bad thing? By making the review process selective it not only gives people something to aspire to but also ensures competence in the reviewers. All to often things are down-rated just because people can not figure out how to use them or exploit their full potential.
Moreover I also agree with Zarel as to why a free-for-all 5-star system does not work in practise. Reviewing a collection of products is not something anyone can do. You need to not only be prolific in order to facilitate comparisons between similar products but also consistent. It takes time, effort and experience. (And, incidentally, why I do not plan on reviewing anything, maps, mods, or otherwise.)
Finally, and possibly the most important point, is that having a small team of reviewers/commentators is crucial because it allows for readers to negate any perceived bias. I'll give an example: Robert Christgau is a well known American rock critic. He has reviewed thousands of albums over the past 30 years or so. He is also incredibly biased and has an extremely unique taste in music. (He gave Pink Floyd's 1973 album Dark Side of the Moon -- one of the best selling albums of all time -- a B and Making Movies by Dire Straits a C+.) So why do people still value his opinion? Simple: because he is biased and he knows it. If you know someone is biased you can compensate for it. Read enough material from a reviewer and you develop the ability to relate their bias to your own.
The problem arises when either the source is not biased (due to many respondents) or has an unknown bias. At this point your opinion is worthless. You say it is "great," and "allows for an excellent multi-player match", but I don't know you, I don't know if we have similar views on what is great and what is average. This kind of relationship between commentator and reader takes time to develop.
In conclusion: ratings are only meaningful when supplemented with comments (which are also helpful for those developing the content in question) and only helpful when you know who made the comments.
As for if this system will be beneficial to content creators. Not without lots of commentary and feedback from fellow content creators, and experienced players (developers or otherwise). Unless, that is, someone has developed a way of converting a number from 1-5 into constructive criticism.
Edit: Just saw this on Slashdot and consider it to be quite poignant:

Polemically yours, Freddie.
