Yedda's system is not as complicated as Yahoo's system. Yedda system is a basic thumbs up or thumbs down, with a one or two thumb option. You can also be ranked by most active this depends on how many questions you answer. The other is top ranked, this is determined by how many questions you answered and the number of thumbs up you received.
Yedda is also like a community of friends, we all get along and yes sometimes our answers don't always agree, but it is like a big family.
