I've been a long time wiki reader for almost 20 years. I first signed up to edit Tony Leung's page because it can really use some work (Chinese version as well).
In my free time, I go through mainly movie and entertainment articles, or whatever I may come across. I think it's important that Wikipedia presents reliable factual information that doesn't contain biased or promotional content, because that is what I want to see as a consumer of the content.
