There really is no specific criteria for a quality contribution. Any contribution that helps out the site of WikiAnswers, whether it be categorizing a question or minor editing a question, is considered good. Generally, however, a good quality contribution comes in the form of an answer. A good quality answer will usually be 2-3 sentences minimum and will be free from spelling or grammar errors (and hopefully false information!). That seems to be the consensus for a quality contribution, but as stated before, any contribution that helps out WikiAnswers is considered a good contribution. A good quality contribution is basically not a wasted contribution. For instance, categorizing and recategorizing the same question 10 times just to gain contribution points is not considered a "good quality contribution." However, categorizing that question properly, answering it with a well-informed answer (free from grammar and spelling mistakes), and adding a related link would count as 3 great quality contributions. Thus, any contribution that helps out WikiAnswers and is not "yes it is because i said so" as an answer, as an example, is a quality contribution.
