A good plan - it's very easy to get wrapped up in serious debate, but that takes away the enjoyment - and yet there are thousands of "fun" articles to add, noncontroversial content that is a necessary part of a comprehensive encyclopedia.
I believe that this indicates that we need a better way to agree (or at least act) on controversial matters.
It is good advice anywhere to avoid burning out on unimportant issues, but that seems especially true at Wikipedia. The amount of frustration that editors suffer trying to resolve something over a single article is high, because the process is unclear, and because of the wide range of attitudes of those involved in the decisions.
