These ratings are a mixed blessing - They can tell you who is agood reliable source of info - but they can be abused - if you don't like a person you can go and rate them a one - it's not advised but people do it - Best thing is to look at peoples posts take 30 or so in different threads and you will build up a picture pretty soon. Some guys who have one star are great - they get rated low beacuse they might be considered controversial or break the rules now and then - that doesn't mean they have good info and posts!
